Wrapper over C-style arguments

Implementations§

source§

impl Args

source

pub unsafe fn new( argc: isize, argv: *const *const u8 ) -> Result<Self, (usize, Utf8Error)>

Creates new instance, but verifies that each string inside are UTF-8.

On error returns pair: (string index, Utf8Error)

The function is safe as long as you pass C style main function arguments.

source

pub unsafe fn new_unchecked(argc: isize, argv: *const *const u8) -> Self

Unchecked version of Args::new

Do it on your own risk

source

pub fn as_slice(&self) -> &[*const u8]

Returns slice of raw C strings

source

pub unsafe fn get_str_by_index(&self, index: usize) -> &str

Retrieves string by index.

No checks, 100% unsafe.
