Struct FileSink 

pub struct FileSink<F: Format> { /* private fields */ }

Available on crate feature std only.

Buffered file sink.

Wraps a std::fs::File in a BufWriter under a mutex. Sink::flush flushes the buffer through to the OS; it does not fsync the underlying file. Use the file directly if a stricter guarantee is needed.

Implementations

impl<F: Format> FileSink<F>

pub fn append<P: AsRef<Path>>(path: P, format: F) -> Result<Self>

Open path for append and wrap it as a sink. Creates the file if it does not exist.

pub fn create<P: AsRef<Path>>(path: P, format: F) -> Result<Self>

Open path for truncating write and wrap it as a sink.
