Methods

impl i32

pub const fn min_value() -> i32

Returns the smallest value that can be represented by this integer type.

Examples

Basic usage:

assert_eq!(i32::min_value(), -2147483648);

pub const fn max_value() -> i32

Returns the largest value that can be represented by this integer type.

Examples

pub fn from_str_radix(src: &str, radix: u32) -> Result<i32, ParseIntError>

Converts a string slice in a given base to an integer.

The string is expected to be an optional + or - sign followed by digits. Leading and trailing whitespace represent an error. Digits are a subset of these characters, depending on radix:

• 0-9
• a-z
• A-Z

Panics

This function panics if radix is not in the range from 2 to 36.

Examples

Basic usage:

#[must_use = "this returns the result of the operation, without modifying the original"] pub fn wrapping_div(self, rhs: i32) -> i32

Wrapping (modular) division. Computes self / rhs, wrapping around at the boundary of the type.

The only case where such wrapping can occur is when one divides MIN / -1 on a signed type (where MIN is the negative minimal value for the type); this is equivalent to -MIN, a positive value that is too large to represent in the type. In such a case, this function returns MIN itself.

Panics

This function will panic if rhs is 0.

Examples

Basic usage:

assert_eq!(100i32.wrapping_div(10), 10);
assert_eq!((-128i8).wrapping_div(-1), -128);

Wrapping Euclidean division. Computes self.div_euclid(rhs), wrapping around at the boundary of the type.

Wrapping will only occur in MIN / -1 on a signed type (where MIN is the negative minimal value for the type). This is equivalent to -MIN, a positive value that is too large to represent in the type. In this case, this method returns MIN itself.

Panics

This function will panic if rhs is 0.

Wrapping (modular) remainder. Computes self % rhs, wrapping around at the boundary of the type.

Such wrap-around never actually occurs mathematically; implementation artifacts make x % y invalid for MIN / -1 on a signed type (where MIN is the negative minimal value). In such a case, this function returns 0.

Panics

This function will panic if rhs is 0.

Examples

Basic usage:

assert_eq!(100i32.wrapping_rem(10), 0);

assert_eq!(i32::min_value().wrapping_neg(), i32::min_value());

#[must_use = "this returns the result of the operation, without modifying the original"] pub const fn wrapping_shl(self, rhs: u32) -> i32

Panic-free bitwise shift-left; yields self << mask(rhs), where mask removes any high-order bits of rhs that would cause the shift to exceed the bitwidth of the type.

Note that this is not the same as a rotate-left; the RHS of a wrapping shift-left is restricted to the range of the type, rather than the bits shifted out of the LHS being returned to the other end. The primitive integer types all implement a rotate_left function, which may be what you want instead.

Examples

Basic usage:

assert_eq!((-1i32).wrapping_shl(7), -128);
assert_eq!((-1i32).wrapping_shl(128), -1);

Basic usage:

assert_eq!(100i32.wrapping_abs(), 100);
assert_eq!((-100i32).wrapping_abs(), 100);

assert_eq!(3i8.overflowing_pow(5), (-13, true));

#[must_use = "this returns the result of the operation, without modifying the original"] pub fn pow(self, exp: u32) -> i32

Raises self to the power of exp, using exponentiation by squaring.

Examples

Basic usage:

let x: i32 = 2; // or any other integer type

assert_eq!(x.pow(5), 32);

#[must_use = "this returns the result of the operation, without modifying the original"] pub fn div_euclid(self, rhs: i32) -> i32

Calculates the quotient of Euclidean division of self by rhs.

This computes the integer n such that self = n * rhs + self.rem_euclid(rhs), with 0 <= self.rem_euclid(rhs) < rhs.

In other words, the result is self / rhs rounded to the integer n such that self >= n * rhs. If self > 0, this is equal to round towards zero (the default in Rust); if self < 0, this is equal to round towards +/- infinity.

Panics

This function will panic if rhs is 0.

Examples

Basic usage:

let a: i32 = 7; // or any other integer type
let b = 4;

assert_eq!(a.div_euclid(b), 1); // 7 >= 4 * 1
assert_eq!(a.div_euclid(-b), -1); // 7 >= -4 * -1
assert_eq!((-a).div_euclid(b), -2); // -7 >= 4 * -2
assert_eq!((-a).div_euclid(-b), 2); // -7 >= -4 * 2

#[must_use = "this returns the result of the operation, without modifying the original"] pub fn rem_euclid(self, rhs: i32) -> i32

Calculates the least nonnegative remainder of self (mod rhs).

This is done as if by the Euclidean division algorithm -- given r = self.rem_euclid(rhs), self = rhs * self.div_euclid(rhs) + r, and 0 <= r < abs(rhs).

Panics

This function will panic if rhs is 0.

Examples

Basic usage:

let a: i32 = 7; // or any other integer type
let b = 4;

assert_eq!(a.rem_euclid(b), 3);
assert_eq!((-a).rem_euclid(b), 1);
assert_eq!(a.rem_euclid(-b), 3);
assert_eq!((-a).rem_euclid(-b), 1);

pub const fn abs(self) -> i32

Computes the absolute value of self.

Overflow behavior

The absolute value of i32::min_value() cannot be represented as an i32, and attempting to calculate it will cause an overflow. This means that code in debug mode will trigger a panic on this case and optimized code will return i32::min_value() without a panic.

Examples

Basic usage:

assert_eq!(10i32.abs(), 10);
assert_eq!((-10i32).abs(), 10);

pub fn signum(self) -> i32

Returns a number representing sign of self.

• 0 if the number is zero
• 1 if the number is positive
• -1 if the number is negative

Examples

Basic usage:

assert_eq!(10i32.signum(), 1);
assert_eq!(0i32.signum(), 0);
assert_eq!((-10i32).signum(), -1);

pub const fn is_positive(self) -> bool

Returns true if self is positive and false if the number is zero or negative.

Examples

Basic usage:

assert!(10i32.is_positive());
assert!(!(-10i32).is_positive());

pub const fn is_negative(self) -> bool

Returns true if self is negative and false if the number is zero or positive.

Examples

Basic usage:

assert!((-10i32).is_negative());
assert!(!10i32.is_negative());

pub fn to_be_bytes(self) -> [u8; 4]

Return the memory representation of this integer as a byte array in big-endian (network) byte order.

Examples

let bytes = 0x12345678i32.to_be_bytes();
assert_eq!(bytes, [0x12, 0x34, 0x56, 0x78]);

pub fn to_le_bytes(self) -> [u8; 4]

Return the memory representation of this integer as a byte array in little-endian byte order.

Examples

let bytes = 0x12345678i32.to_le_bytes();
assert_eq!(bytes, [0x78, 0x56, 0x34, 0x12]);

pub fn to_ne_bytes(self) -> [u8; 4]

Return the memory representation of this integer as a byte array in native byte order.

As the target platform's native endianness is used, portable code should use to_be_bytes or to_le_bytes, as appropriate, instead.

Examples

let bytes = 0x12345678i32.to_ne_bytes();
assert_eq!(
    bytes,
    if cfg!(target_endian = "big") {
        [0x12, 0x34, 0x56, 0x78]
    } else {
        [0x78, 0x56, 0x34, 0x12]
    }
);

pub fn from_be_bytes(bytes: [u8; 4]) -> i32

Create an integer value from its representation as a byte array in big endian.

Examples

let value = i32::from_be_bytes([0x12, 0x34, 0x56, 0x78]);
assert_eq!(value, 0x12345678);

When starting from a slice rather than an array, fallible conversion APIs can be used:

use std::convert::TryInto;

fn read_be_i32(input: &mut &[u8]) -> i32 {
    let (int_bytes, rest) = input.split_at(std::mem::size_of::<i32>());
    *input = rest;
    i32::from_be_bytes(int_bytes.try_into().unwrap())
}

pub fn from_le_bytes(bytes: [u8; 4]) -> i32

Create an integer value from its representation as a byte array in little endian.

Examples

let value = i32::from_le_bytes([0x78, 0x56, 0x34, 0x12]);
assert_eq!(value, 0x12345678);

When starting from a slice rather than an array, fallible conversion APIs can be used:

use std::convert::TryInto;

fn read_le_i32(input: &mut &[u8]) -> i32 {
    let (int_bytes, rest) = input.split_at(std::mem::size_of::<i32>());
    *input = rest;
    i32::from_le_bytes(int_bytes.try_into().unwrap())
}

pub fn from_ne_bytes(bytes: [u8; 4]) -> i32

Create an integer value from its memory representation as a byte array in native endianness.

As the target platform's native endianness is used, portable code likely wants to use from_be_bytes or from_le_bytes, as appropriate instead.

Examples

let value = i32::from_ne_bytes(if cfg!(target_endian = "big") {
    [0x12, 0x34, 0x56, 0x78]
} else {
    [0x78, 0x56, 0x34, 0x12]
});
assert_eq!(value, 0x12345678);

When starting from a slice rather than an array, fallible conversion APIs can be used:

use std::convert::TryInto;

fn read_ne_i32(input: &mut &[u8]) -> i32 {
    let (int_bytes, rest) = input.split_at(std::mem::size_of::<i32>());
    *input = rest;
    i32::from_ne_bytes(int_bytes.try_into().unwrap())
}
