Struct bonsaidb::files::direct::AsyncBufferedAppend

pub struct AsyncBufferedAppend<'a, Config, Database>where
    Config: FileConfig,
    Database: AsyncConnection + Clone + 'static,{ /* private fields */ }

A buffered [tokio::io::AsyncWrite] and std::io::Seek implementor for a File.

Implementations

impl<'a, Config, Database> AsyncBufferedAppend<'a, Config, Database>where Config: FileConfig, Database: AsyncConnection + Clone + 'static,

pub async fn set_buffer_size( &mut self, capacity: usize ) -> impl Future<Output = Result<(), Error>>

Sets the size of the buffer. For optimal use, this should be a multiple of Config::BLOCK_SIZE.

If any data is already buffered, it will be flushed before the buffer is resized.

Trait Implementations

impl<'a, Config, Database> AsyncWrite for AsyncBufferedAppend<'a, Config, Database>where Config: FileConfig, Database: AsyncConnection + Clone + 'static,

fn poll_write( self: Pin<&mut AsyncBufferedAppend<'a, Config, Database>>, cx: &mut Context<'_>, data: &[u8] ) -> Poll<Result<usize, Error>>

Attempt to write bytes from buf into the object.

fn poll_flush( self: Pin<&mut AsyncBufferedAppend<'a, Config, Database>>, 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 AsyncBufferedAppend<'a, Config, Database>>, 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<'a, Config, Database> Drop for AsyncBufferedAppend<'a, Config, Database>where Config: FileConfig, Database: AsyncConnection + Clone + 'static,

fn drop(&mut self)

Executes the destructor for this type.
