Trait MessageBody 

pub trait MessageBody: 'static {
    // Required methods
    fn size(&self) -> BodySize;
    fn poll_next_chunk(
        &mut self,
        cx: &mut Context<'_>,
    ) -> Poll<Option<Result<Bytes, Rc<dyn Error>>>>;
}

Interface for types that can be streamed to a peer.

Required Methods

fn size(&self) -> BodySize

Returns the body size hint.

fn poll_next_chunk( &mut self, cx: &mut Context<'_>, ) -> Poll<Option<Result<Bytes, Rc<dyn Error>>>>

Polls the next body chunk.

Dyn Compatibility

This trait is dyn compatible.

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