Trait StrExt 

pub trait StrExt {
    // Required methods
    fn repeat(&self, times: usize) -> String;
    fn to_lowercase(&self) -> String;
    fn to_uppercase(&self) -> String;
    fn to_ascii_uppercase(&self) -> String;
    fn to_ascii_lowercase(&self) -> String;
}

Extension trait to override methods that returns std’s String

Required Methods

fn repeat(&self, times: usize) -> String

Creates a new String by repeating a string times.

Panics

This function will panic if the capacity would overflow.

fn to_lowercase(&self) -> String

Returns the lowercase equivalent of this string slice, as a new String.

fn to_uppercase(&self) -> String

Returns the uppercase equivalent of this string slice, as a new String.

fn to_ascii_uppercase(&self) -> String

Returns a copy of this string where each character is mapped to its ASCII upper case equivalent.

ASCII letters ‘a’ to ‘z’ are mapped to ‘A’ to ‘Z’, but non-ASCII letters are unchanged.

fn to_ascii_lowercase(&self) -> String

Returns a copy of this string where each character is mapped to its ASCII lower case equivalent.

ASCII letters ‘A’ to ‘Z’ are mapped to ‘a’ to ‘z’, but non-ASCII letters are unchanged.
