Struct opendal::BlockingWriter

pub struct BlockingWriter { /* private fields */ }

BlockingWriter is designed to write data into given path in an blocking manner.

Implementations

impl BlockingWriter

pub fn append(&mut self, bs: impl Into<Bytes>) -> Result<()>

Append data into writer.

It is highly recommended to align the length of the input bytes into blocks of 4MiB (except the last block) for better performance and compatibility.

pub fn close(&mut self) -> Result<()>

Close the writer and make sure all data have been stored.

Trait Implementations

impl Write for BlockingWriter

fn write(&mut self, buf: &[u8]) -> Result<usize>

Write a buffer into this writer, returning how many bytes were written.

fn flush(&mut self) -> Result<()>

Flush this output stream, ensuring that all intermediately buffered contents reach their destination.

fn write_vectored(&mut self, bufs: &[IoSlice<'_>]) -> Result<usize, Error>

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

fn is_write_vectored(&self) -> bool

🔬This is a nightly-only experimental API. (can_vector)

Determines if this Writer has an efficient write_vectored implementation.

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

Attempts to write an entire buffer into this writer.

fn write_all_vectored(&mut self, bufs: &mut [IoSlice<'_>]) -> Result<(), Error>

🔬This is a nightly-only experimental API. (write_all_vectored)

Attempts to write multiple buffers into this writer.

fn write_fmt(&mut self, fmt: Arguments<'_>) -> Result<(), Error>

Writes a formatted string into this writer, returning any error encountered.

fn by_ref(&mut self) -> &mut Selfwhere Self: Sized,

Creates a “by reference” adapter for this instance of Write.
