Function find_skip 

pub const fn find_skip<'a>(this: &'a str, needle: &str) -> Option<&'a str>

Advances this past the first instance of needle.

Return None if no instance of needle is found.

Return Some(this) if needle is empty.

Motivation

This function exists because calling find + str_from when the "rust_1_64" feature is disabled is slower than it could be, since the slice has to be traversed twice.

Example

use konst::string;

{
    const FOUND: Option<&str> = string::find_skip("foo bar baz", "bar");
    assert_eq!(FOUND, Some(" baz"));
}
{
    const NOT_FOUND: Option<&str> = string::find_skip("foo bar baz", "qux");
    assert_eq!(NOT_FOUND, None);
}
{
    const EMPTY_NEEDLE: Option<&str> = string::find_skip("foo bar baz", "");
    assert_eq!(EMPTY_NEEDLE, Some("foo bar baz"));
}
