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 write(&mut self, bs: impl Into<Buffer>) -> Result<()>

Write Buffer into writer.

This operation will write all data in given buffer into writer.

Examples

use bytes::Bytes;
use opendal::BlockingOperator;
use opendal::Result;

async fn test(op: BlockingOperator) -> Result<()> {
    let mut w = op.writer("hello.txt")?;
    // Buffer can be created from continues bytes.
    w.write("hello, world")?;
    // Buffer can also be created from non-continues bytes.
    w.write(vec![Bytes::from("hello,"), Bytes::from("world!")])?;

    // Make sure file has been written completely.
    w.close()?;
    Ok(())
}

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

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

Notes

Close should only be called when the writer is not closed or aborted, otherwise an unexpected error could be returned.

pub fn into_std_write(self) -> StdWriter

Convert writer into StdWriter which implements std::io::Write,
