1.0.0[−][src]Struct std::env::Args
An iterator over the arguments of a process, yielding a String
value for
each argument.
This struct is created by the std::env::args
function. See its
documentation for more.
The first element is traditionally the path of the executable, but it can be set to arbitrary text, and may not even exist. This means this property should not be relied upon for security purposes.
