Struct EncodeBody

Source 
pub struct EncodeBody<T, U> { /* private fields */ }
Expand description

A specialized implementation of Body for encoding Result<Bytes, Status>.

Implementations§

Source§

impl<T, U> EncodeBody<T, U>
where T: Encoder, U: Stream,

Source

pub fn new_client( encoder: T, source: U, compression_encoding: Option<CompressionEncoding>, max_message_size: Option<usize>, ) -> EncodeBody<T, U>

Turns a stream of grpc messages into EncodeBody which is used by grpc clients for turning the messages into http frames for sending over the network.

Source

pub fn new_server( encoder: T, source: U, compression_encoding: Option<CompressionEncoding>, compression_override: SingleMessageCompressionOverride, max_message_size: Option<usize>, ) -> EncodeBody<T, U>

Turns a stream of grpc results (message or error status) into EncodeBody which is used by grpc servers for turning the messages into http frames for sending over the network.
