Struct actix_http::h1::Payload
source · [−]pub struct Payload { /* private fields */ }
Expand description
Buffered stream of bytes chunks
Payload stores chunks in a vector. First chunk can be received with poll_next
. Payload does
not notify current task when new data is available.
Payload can be used as Response
body stream.
Implementations
sourceimpl Payload
impl Payload
sourcepub fn create(eof: bool) -> (PayloadSender, Payload)
pub fn create(eof: bool) -> (PayloadSender, Payload)
Creates a payload stream.
This method construct two objects responsible for bytes stream generation:
PayloadSender
- Sender side of the streamPayload
- Receiver side of the stream
sourcepub fn unread_data(&mut self, data: Bytes)
pub fn unread_data(&mut self, data: Bytes)
Put unused data back to payload
