ClientTransaction

Struct ClientTransaction 

pub struct ClientTransaction<'a, IO> { /* private fields */ }
Available on crate features icap and std only.
Expand description

A streaming ICAP request body being sent by a client.

Implementations§

§

impl<'a, IO> ClientTransaction<'a, IO>
where IO: Io + Unpin + ExtensionsRef,

pub async fn write_data(&mut self, data: &[u8]) -> Result<WriteOutcome, Error>

Write one entity-body data segment as an ICAP chunk.

Preview segments may not exceed the advertised Preview limit. The caller retains ownership of the source body and decides how to replay preview bytes after a final 204 or 206 response.

pub async fn monitor_response(&mut self) -> Result<WriteOutcome, Error>

Wait for an early final response while the body source is idle.

write_data monitors the read side while each segment is written. Callers waiting asynchronously for the next source segment must race that wait with this method so early ICAP responses are always consumed. The transaction keeps accepting body data after a non-closing, bodyless response. A body-bearing response automatically takes the transport-close fallback so its body can be streamed.

pub async fn finish(self) -> Result<ClientResponse<'a, IO>, Error>

Finish a non-Preview request and read its final response head.

pub async fn finish_with_trailers( self, trailers: &TrailerBlock, ) -> Result<ClientResponse<'a, IO>, Error>

Finish a non-Preview request with negotiated HTTP trailers.

pub async fn abandon(self) -> Result<ClientResponse<'a, IO>, Error>

Stop sending after an early final response and close the write side.

Finishing a bodyless response path is preferred. This explicit fallback satisfies the ICAP requirement to terminate the transport when the remainder is not sent. Body-bearing early responses already take this fallback automatically.

pub async fn finish_preview( self, end_of_body: bool, ) -> Result<PreviewOutcome<'a, IO>, Error>

Finish a Preview and read either 100 Continue or a final response.

Set end_of_body only when the supplied preview contains the complete entity body. This emits the ieof terminal extension.

pub async fn finish_preview_with_trailers( self, end_of_body: bool, trailers: &TrailerBlock, ) -> Result<PreviewOutcome<'a, IO>, Error>

Finish a Preview with negotiated HTTP trailers.
