Struct termcolor::Buffer

pub struct Buffer(_);

Write colored text to memory.

Buffer is a platform independent abstraction for printing colored text to an in memory buffer. When the buffer is printed using a BufferWriter, the color information will be applied to the output device (a tty on Unix and a console on Windows).

A Buffer is typically created by calling the BufferWriter.buffer method, which will take color preferences and the environment into account. However, buffers can also be manually created using no_color, ansi or console (on Windows).

Methods

impl Buffer

Important traits for Buffer

impl Write for Buffer

pub fn no_color() -> Buffer

Create a buffer that drops all color information.

Important traits for Buffer

impl Write for Buffer

pub fn ansi() -> Buffer

Create a buffer that uses ANSI escape sequences.

pub fn is_empty(&self) -> bool

Returns true if and only if this buffer is empty.

pub fn len(&self) -> usize

Returns the length of this buffer in bytes.

pub fn clear(&mut self)

Clears this buffer.

pub fn into_inner(self) -> Vec<u8>

Consume this buffer and return the underlying raw data.

On Windows, this unrecoverably drops all color information associated with the buffer.

pub fn as_slice(&self) -> &[u8]

Return the underlying data of the buffer.

pub fn as_mut_slice(&mut self) -> &mut [u8]

Return the underlying data of the buffer as a mutable slice.

Trait Implementations

impl Write for Buffer

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

Write a buffer into this object, 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<(), Error>

Attempts to write an entire buffer into this write.

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 Buffer

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.
