Struct tonic::Streaming[][src]

pub struct Streaming<T> { /* fields omitted */ }

Streaming requests and responses.

This will wrap some inner Body and Decoder and provide an interface to fetch the message stream and trailing metadata

Implementations

impl<T> Streaming<T>[src]

pub async fn message(&mut self) -> Result<Option<T>, Status>[src]

Fetch the next message from this stream.

if let Some(next_message) = request.message().await? {
    println!("{:?}", next_message);
}

pub async fn trailers(&mut self) -> Result<Option<MetadataMap>, Status>[src]

Fetch the trailing metadata.

This will drain the stream of all its messages to receive the trailing metadata. If Streaming::message returns None then this function will not need to poll for trailers since the body was totally consumed.

if let Some(metadata) = request.trailers().await? {
    println!("{:?}", metadata);
}
