Struct opendal::StdWriter

pub struct StdWriter { /* private fields */ }

StdWriter is the adapter of std::io::Write for BlockingWriter.

Users can use this adapter in cases where they need to use std::io::Write related trait.

Notes

Files are automatically closed when they go out of scope. Errors detected on closing are ignored by the implementation of Drop. Use the method close if these errors must be manually handled.

Implementations

impl StdWriter

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

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

Trait Implementations

impl Drop for StdWriter

fn drop(&mut self)

Executes the destructor for this type.

impl Write for StdWriter

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 Self

where Self: Sized,

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