Trait SplitCharFromStr

pub trait SplitCharFromStr<'a>: Sealed + Sized {
    // Required methods
    fn split_first_char(self) -> Option<(char, &'a str)>;
    fn split_last_char(self) -> Option<(&'a str, char)>;
}

Extension trait that provides methods to split character from a &str.

Required Methods

fn split_first_char(self) -> Option<(char, &'a str)>

Split a string into a pair of first character and the rest.

assert_eq!("abc".split_first_char(), Some(('a', "bc")))

fn split_last_char(self) -> Option<(&'a str, char)>

Split a string into a pair of initial part and the last character.

assert_eq!("abc".split_last_char(), Some(("ab", 'c')))

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
