Struct FileProxy 

pub struct FileProxy<T: ProxyTarget, F: Write> { /* private fields */ }

A writer that sends text through a live display. Mirrors rich.file_proxy.FileProxy; the line buffer lives in the display, so a partial line survives from one proxy to the next, as it does on the one sys.stdout upstream.

Implementations

impl<T: ProxyTarget, F: Write> FileProxy<T, F>

pub fn new(target: T, stream: ProxyStream, file: F) -> Self

A proxy for stream that prints through target, writing to file when the display is not redirecting.

pub fn rich_proxied_file(&self) -> &F

The proxied file. Port of FileProxy.rich_proxied_file; Python’s fileno and isatty forward to it, which here is the caller’s to do.

pub fn stream(&self) -> ProxyStream

Which stream this proxy stands in for.

pub fn into_inner(self) -> F

Consume the proxy, returning the proxied file.

Trait Implementations

impl<T: ProxyTarget, F: Write> Write for FileProxy<T, F>

fn write(&mut self, bytes: &[u8]) -> Result<usize>

Writes a buffer into this writer, returning how many bytes were written.

fn flush(&mut self) -> Result<()>

Flushes 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, args: 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.
