Expand description

Satisfies WriteColor but ignores all color options.

Implementations§

source§

impl<W: Write> NoColor<W>

source

pub fn new(wtr: W) -> NoColor<W>

source

pub fn into_inner(self) -> W

Consume this NoColor value and return the inner writer.

source

pub fn get_ref(&self) -> &W

Return a reference to the inner writer.

source

pub fn get_mut(&mut self) -> &mut W

Return a mutable reference to the inner writer.
