Struct NoColor

pub struct NoColor<W>(/* private fields */);

Satisfies WriteColor but ignores all color options.

Implementations

impl<W: Write> NoColor<W>

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

Create a new writer that satisfies WriteColor but drops all color information.

pub fn into_inner(self) -> W

Consume this NoColor value and return the inner writer.

pub fn get_ref(&self) -> &W

Return a reference to the inner writer.

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

Return a mutable reference to the inner writer.

Trait Implementations

impl<W: Clone> Clone for NoColor<W>

fn clone(&self) -> NoColor<W>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<W: Debug> Debug for NoColor<W>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<W: Write> Write for NoColor<W>

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

Writes a buffer into this writer, returning how many bytes were written.

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

Flushes 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 is_write_vectored(&self) -> bool

🔬This is a nightly-only experimental API. (can_vector)

Determines if this Writer has an efficient write_vectored implementation.

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

Attempts to write an entire buffer into this writer.

fn write_all_vectored(&mut self, bufs: &mut [IoSlice<'_>]) -> Result<(), Error>

🔬This is a nightly-only experimental API. (write_all_vectored)

Attempts to write multiple buffers 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

where Self: Sized,

Creates a “by reference” adapter for this instance of Write.

impl<W: Write> WriteColor for NoColor<W>

fn supports_color(&self) -> bool

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

fn supports_hyperlinks(&self) -> bool

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

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

Set the color settings of the writer.

fn set_hyperlink(&mut self, _: &HyperlinkSpec<'_>) -> Result<()>

Set the current hyperlink 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.
