Struct DirectWriter

pub struct DirectWriter<'a, S: HandleOwner> { /* private fields */ }

Like object_handle::Writer, but allows custom transaction options to be set, and makes every write go directly to the handle in a transaction.

Implementations

impl<'a, S: HandleOwner> DirectWriter<'a, S>

pub async fn new( handle: &'a DataObjectHandle<S>, options: Options<'a>, ) -> DirectWriter<'a, S>

Trait Implementations

impl<S: HandleOwner> Drop for DirectWriter<'_, S>

fn drop(&mut self)

Executes the destructor for this type.

impl<'a, S: HandleOwner> WriteBytes for DirectWriter<'a, S>

fn block_size(&self) -> u64

async fn write_bytes(&mut self, buf: &[u8]) -> Result<(), Error>

Buffers writes to be written to the underlying handle. This may flush bytes immediately or when buffers are full.

async fn complete(&mut self) -> Result<(), Error>

Called to flush to the handle. Named to avoid conflict with the flush method above.

async fn skip(&mut self, amount: u64) -> Result<(), Error>

Moves the offset forward by amount, which will result in zeroes in the output stream, even if no other data is appended to it.
