Struct fs::FsPool

pub struct FsPool { /* private fields */ }

A pool of threads to handle file IO.

Implementations

impl FsPool

pub fn new(threads: usize) -> Self

Creates a new FsPool, with the supplied number of threads.

pub fn with_executor<E>(executor: E) -> Selfwhere E: Executor<Box<dyn Future<Item = (), Error = ()> + Send>> + Send + Sync + 'static,

Creates a new FsPool, from an existing Executor.

Note

The executor will be used to spawn tasks that can block the thread. It likely should not be an executor that is also handling light-weight tasks, but a dedicated thread pool.

The most common use of this constructor is to allow creating a single CpuPool for your application for blocking tasks, and sharing it with FsPool and any other things needing a thread pool.

pub fn read<P>(&self, path: P, opts: ReadOptions) -> FsReadStreamwhere P: AsRef<Path> + Send + 'static,

Returns a Stream of the contents of the file at the supplied path.

pub fn read_file(&self, file: File, opts: ReadOptions) -> FsReadStream

Returns a Stream of the contents of the supplied file.

pub fn write<P>(&self, path: P, opts: WriteOptions) -> FsWriteSinkwhere P: AsRef<Path> + Send + 'static,

Returns a Sink to send bytes to be written to the file at the supplied path.

pub fn write_file(&self, file: File) -> FsWriteSink

Returns a Sink to send bytes to be written to the supplied file.

pub fn delete<P>(&self, path: P) -> FsFuture<()>where P: AsRef<Path> + Send + 'static,

Returns a Future that resolves when the target file is deleted.
