AsyncResponseStaging

Struct AsyncResponseStaging 

Source
pub struct AsyncResponseStaging<'staging, 'buffer> { /* private fields */ }
Expand description

Non-committing response view supplied to an asynchronous transport.

Implementations may initialize body and header storage, but this type deliberately exposes no commit operation. Cancellation drops the SDK-owned outer attempt and clears all partial state.

use cloud_sdk::transport::{AsyncResponseStaging, ResponseMetadata, StatusCode};
fn cannot_commit(mut staging: AsyncResponseStaging<'_, '_>) {
    staging.commit(StatusCode::OK, 0, ResponseMetadata::EMPTY);
}

Implementations§

Source§

impl<'buffer> AsyncResponseStaging<'_, 'buffer>

Source

pub fn headers_mut( &mut self, ) -> Result<&mut ResponseHeaders<'buffer>, ResponseWriterError>

Returns mutable caller-owned response-header storage.

Source

pub const fn headers(&self) -> &ResponseHeaders<'buffer>

Returns response headers captured so far.
