Struct log4rs::encode::writer::console::ConsoleWriter

pub struct ConsoleWriter(_);

An encode::Writer that outputs to a console.

Implementations

impl ConsoleWriter

pub fn stdout() -> Option<ConsoleWriter>

Returns a new ConsoleWriter that will write to standard out.

Returns None if standard out is not a console buffer on Windows, and if it is not a TTY on Unix.

pub fn stderr() -> Option<ConsoleWriter>

Returns a new ConsoleWriter that will write to standard error.

Returns None if standard error is not a console buffer on Windows, and if it is not a TTY on Unix.

pub fn lock<'a>(&'a self) -> ConsoleWriterLock<'a>

Locks the console, preventing other threads from writing concurrently.

Trait Implementations

impl Write for ConsoleWriter

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

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

impl Write for ConsoleWriter

fn set_style(&mut self, style: &Style) -> Result<()>

Sets the output text style, if supported.
