Struct tracing_subscriber::fmt::writer::ArcWriter

pub struct ArcWriter<W>(_);

This is supported on crate feature fmt only.

Implements std::io::Write for an Arc where &W: Write.

This is an implementation detail of the MakeWriter impl for Arc.

Trait Implementations

impl<W: Clone> Clone for ArcWriter<W>

fn clone(&self) -> ArcWriter<W>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<W: Debug> Debug for ArcWriter<W>

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

Formats the value using the given formatter.

impl<W> Write for ArcWriter<W> where
    for<'a> &'a W: Write, 

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

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

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

Flush this output stream, ensuring that all intermediately buffered contents reach their destination.

fn write_vectored(&mut self, bufs: &[IoSlice<'_>]) -> Result<usize>

Like write, except that it writes from a slice of buffers.

fn write_all(&mut self, buf: &[u8]) -> Result<()>

Attempts to write an entire buffer into this writer.

fn write_fmt(&mut self, fmt: Arguments<'_>) -> Result<()>

Writes a formatted string into this writer, returning any error encountered.

fn is_write_vectored(&self) -> bool

🔬 This is a nightly-only experimental API. (can_vector #69941)

Determines if this Writer has an efficient write_vectored implementation.

fn write_all_vectored(&mut self, bufs: &mut [IoSlice<'_>]) -> Result<(), Error>

🔬 This is a nightly-only experimental API. (write_all_vectored #70436)

Attempts to write multiple buffers into this writer.

fn by_ref(&mut self) -> &mut Self

Creates a “by reference” adapter for this instance of Write.
