Trait Utf8Len 

pub trait Utf8Len {
    // Required methods
    fn utf8_len_at<T>(&self, idx: T) -> usize
       where usize: Cast<T>;
    fn utf8_count(&self) -> usize;
    fn utf8_slice(&self, r: impl uRange) -> &str;
    fn slice(&self, r: impl uRange) -> &str;
}

Required Methods

fn utf8_len_at<T>(&self, idx: T) -> usize

where usize: Cast<T>,

fn utf8_count(&self) -> usize

fn utf8_slice(&self, r: impl uRange) -> &str

fn slice(&self, r: impl uRange) -> &str

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.
