Struct `BufferWriter`

pub struct BufferWriter { /* private fields */ }

Writes colored buffers to stdout or stderr.

Writable buffers can be obtained by calling buffer on a BufferWriter.

This writer works with terminals that support ANSI escape sequences or with a Windows console.

It is intended for a BufferWriter to be put in an Arc and written to from multiple threads simultaneously.

Implementations

`impl BufferWriter`

fn stdout(choice: ColorChoice) -> BufferWriter

Create a new BufferWriter that writes to stdout with the given color preferences.

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 to the buffers themselves.

fn stderr(choice: ColorChoice) -> BufferWriter

Create a new BufferWriter that writes to stderr with the given color preferences.

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 to the buffers themselves.

fn separator(&mut self, sep: Option<Vec<u8>>)

If set, the separator given is printed between buffers. By default, no separator is printed.

The default value is None.

fn buffer(&self) -> Buffer

Creates a new Buffer with the current color preferences.

A Buffer satisfies both io::Write and WriteColor. A Buffer can be printed using the print method.

fn print(&self, buf: &Buffer) -> Result<()>

Prints the contents of the given buffer.

It is safe to call this from multiple threads simultaneously. In particular, all buffers are written atomically. No interleaving will occur.
