Struct Upload

pub struct Upload<E> { /* private fields */ }

Upload is a sink that implements the lifecycle of a single multipart upload. It writes items to an inner AsyncWrite that periodically adds parts to the upload, then completes the upload when the inner writer has uploaded enough parts, bytes, or whatever else would make the method UploadControl::is_upload_ready return true.

Implementations

impl<E> Upload<E>

pub fn new<C, U>( client: U, ctrl: C, encoder: E, params: UploadRequestParams, ) -> Self

where C: UploadControl + Send + Sync + 'static, U: UploadClient + Send + Sync + 'static,

Trait Implementations

impl<E, I> Sink<I> for Upload<E>

where E: Encoder<I> + Clone, E::Error: From<Error>, AwsError: From<E::Error>,

type Error = AwsError

The type of value produced by the sink when an error occurs.

fn poll_ready( self: Pin<&mut Self>, cx: &mut Context<'_>, ) -> Poll<Result<(), Self::Error>>

Attempts to prepare the Sink to receive a value.

fn start_send(self: Pin<&mut Self>, item: I) -> Result<(), Self::Error>

Begin the process of sending a value to the sink. Each call to this function must be preceded by a successful call to poll_ready which returned Poll::Ready(Ok(())).

fn poll_flush( self: Pin<&mut Self>, cx: &mut Context<'_>, ) -> Poll<Result<(), Self::Error>>

Flush any remaining output from this sink.

fn poll_close( self: Pin<&mut Self>, cx: &mut Context<'_>, ) -> Poll<Result<(), Self::Error>>

Flush any remaining output and close this sink, if necessary.

impl<'__pin, E> Unpin for Upload<E>
