Trait ReadHalf 

pub trait ReadHalf: Debug {
    // Required method
    fn read(
        &mut self,
        buf: &mut [u8],
    ) -> impl Future<Output = Result<ReadResult>>;
}

The read half of a socket.

Required Methods

fn read(&mut self, buf: &mut [u8]) -> impl Future<Output = Result<ReadResult>>

Read from a socket.

On completion, the number of bytes read and any file descriptors received are returned.

Notes for implementers:

• The future returned by this method must be cancel safe.
• While there is no explicit Unpin bound on the future returned by this method, it is expected that it provides the same guarentees as Unpin would require. The reason Unpin is not explicitly requied is that it would force boxing (and therefore allocation) on the implemention that use async fn, which is undesirable for embedded use cases. See this issue for details.

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.
