Trait Code

pub trait Code<T>: Sized {
    type Item;

    // Required methods
    fn code(&mut self, item: T) -> Result<Option<Self::Item>>;
    fn code_eof(&mut self) -> Result<Option<Self::Item>>;

    // Provided method
    fn size_hint(&self, stream: &impl Stream) -> (usize, Option<usize>) { ... }
}

Required Associated Types

type Item

Required Methods

fn code(&mut self, item: T) -> Result<Option<Self::Item>>

fn code_eof(&mut self) -> Result<Option<Self::Item>>

Provided Methods

fn size_hint(&self, stream: &impl Stream) -> (usize, Option<usize>)

A helper method for overriding associated input stream’s size_hint. by default it returns value the same as Stream::size_hint’s default value. in other word the default prediction is (de)compress can not hint an exact size.

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.
