Expand description

Provides a fn to read a varint from an AsyncRead source.

Required Methods§

Source

fn read_varint_u64(&mut self) -> impl Future<Output = Result<Option<u64>>>

Reads a u64 varint from an AsyncRead source, using the Postcard/LEB128 format.

If the stream is at the end, this returns Ok(None).

Source

fn read_length_prefixed<T: DeserializeOwned>( &mut self, max_size: usize, ) -> impl Future<Output = Result<T>>

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
