Struct glommio::io::StreamWriterBuilder

pub struct StreamWriterBuilder { /* fields omitted */ }

Builds a StreamWriter, allowing linear write access to a BufferedFile

Implementations

impl StreamWriterBuilder

pub fn new(file: BufferedFile) -> StreamWriterBuilder

Creates a new StreamWriterBuilder, given a BufferedFile

Various properties can be set by using its with methods.

A StreamWriter can later be constructed from it by calling build

Examples

use glommio::{
    io::{BufferedFile, StreamWriterBuilder},
    LocalExecutor,
};

let ex = LocalExecutor::default();
ex.run(async {
    let file = BufferedFile::create("myfile.txt").await.unwrap();
    let _reader = StreamWriterBuilder::new(file).build();
});

pub fn with_sync_on_close_disabled(self, flush_disabled: bool) -> Self

Chooses whether or not to issue a sync operation when closing the file (default enabled). Disabling this is dangerous and in most cases may lead to data loss upon power failure.

pub fn with_buffer_size(self, buffer_size: usize) -> Self

Define the buffer size that will be used by the StreamWriter

pub fn build(self) -> StreamWriter

Builds a StreamWriter with the properties defined by this StreamWriterBuilder

Trait Implementations

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
