Struct tvix_castore::blobservice::grpc::GRPCBlobWriter

pub struct GRPCBlobWriter<W: AsyncWrite> {
    task_and_writer: Option<(JoinHandle<Result<PutBlobResponse, Status>>, W)>,
    digest: Option<B3Digest>,
}

Fields

task_and_writer: Option<(JoinHandle<Result<PutBlobResponse, Status>>, W)>

The task containing the put request, and the inner writer, if we’re still writing.

digest: Option<B3Digest>

The digest that has been returned, if we successfully closed.

Trait Implementations

impl<W: AsyncWrite + Unpin> AsyncWrite for GRPCBlobWriter<W>

fn poll_write( self: Pin<&mut Self>, cx: &mut Context<'_>, buf: &[u8], ) -> Poll<Result<usize, Error>>

Attempt to write bytes from buf into the object.

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

Attempts to flush the object, ensuring that any buffered data reach their destination.

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

Initiates or attempts to shut down this writer, returning success when the I/O connection has completely shut down.

fn poll_write_vectored( self: Pin<&mut Self>, cx: &mut Context<'_>, bufs: &[IoSlice<'_>], ) -> Poll<Result<usize, Error>>

Like poll_write, except that it writes from a slice of buffers.

fn is_write_vectored(&self) -> bool

Determines if this writer has an efficient poll_write_vectored implementation.

impl<W: AsyncWrite + Send + Sync + Unpin + 'static> BlobWriter for GRPCBlobWriter<W>

fn close<'life0, 'async_trait>( &'life0 mut self, ) -> Pin<Box<dyn Future<Output = Result<B3Digest>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Signal there’s no more data to be written, and return the digest of the contents written.
