Struct termcolor::StandardStream

pub struct StandardStream { /* fields omitted */ }

Satisfies io::Write and WriteColor, and supports optional coloring to either of the standard output streams, stdout and stderr.

Methods

impl StandardStream

Important traits for StandardStream

impl Write for StandardStream

pub fn stdout(choice: ColorChoice) -> StandardStream

Create a new StandardStream with the given color preferences that writes to standard output.

On Windows, if coloring is desired and a Windows console could not be found, then ANSI escape sequences are used instead.

The specific color/style settings can be configured when writing via the WriteColor trait.

Important traits for StandardStream

impl Write for StandardStream

pub fn stderr(choice: ColorChoice) -> StandardStream

Create a new StandardStream with the given color preferences that writes to standard error.

On Windows, if coloring is desired and a Windows console could not be found, then ANSI escape sequences are used instead.

The specific color/style settings can be configured when writing via the WriteColor trait.

Important traits for StandardStreamLock<'a>

impl<'a> Write for StandardStreamLock<'a>

pub fn lock(&self) -> StandardStreamLock

Lock the underlying writer.

The lock guard returned also satisfies io::Write and WriteColor.

This method is not reentrant. It may panic if lock is called while a StandardStreamLock is still alive.

Trait Implementations

impl Write for StandardStream

fn write(&mut self, b: &[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, Error>

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

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

Attempts to write an entire buffer into this writer.

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

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

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

Creates a "by reference" adaptor for this instance of Write.

impl WriteColor for StandardStream

fn supports_color(&self) -> bool

Returns true if and only if the underlying writer supports colors.

fn set_color(&mut self, spec: &ColorSpec) -> Result<()>

Set the color settings of the writer.

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

Reset the current color settings to their original settings.

fn is_synchronous(&self) -> bool

Returns true if and only if the underlying writer must synchronously interact with an end user's device in order to control colors. By default, this always returns false.
