Trait FormatBuf 

pub trait FormatBuf:
    Extend<Self::Char>
    + Default
    + FromIterator<Self::Char>
    + From<String> {
    type Char: FormatChar;

    // Required methods
    fn chars(&self) -> impl Iterator<Item = Self::Char>;
    fn len(&self) -> usize;
    fn concat(self, other: Self) -> Self;

    // Provided method
    fn is_empty(&self) -> bool { ... }
}

Required Associated Types

type Char: FormatChar

Required Methods

fn chars(&self) -> impl Iterator<Item = Self::Char>

fn len(&self) -> usize

fn concat(self, other: Self) -> Self

Provided Methods

fn is_empty(&self) -> bool

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.
