Struct `Buffer`

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).

Implementations

`impl Buffer`

fn no_color() -> Buffer

Create a buffer that drops all color information.

fn ansi() -> Buffer

Create a buffer that uses ANSI escape sequences.

fn is_empty(self: &Self) -> bool

Returns true if and only if this buffer is empty.

fn len(self: &Self) -> usize

Returns the length of this buffer in bytes.

fn clear(self: &mut Self)

Clears this buffer.

fn into_inner(self: Self) -> Vec<u8>

Consume this buffer and return the underlying raw data.

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

fn as_slice(self: &Self) -> &[u8]

Return the underlying data of the buffer.

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

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