Trait Implementations

impl Clone for NoWriter

fn clone(&self) -> NoWriter

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for NoWriter

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

Formats the value using the given formatter.

impl Default for NoWriter

fn default() -> NoWriter

Returns the “default value” for a type.

impl<'a> MakeWriter<'a> for NoWriter

type Writer = NoWriter

The concrete fmt::Write implementation returned by make_writer.

fn make_writer(&'a self) -> Self::Writer

Returns an instance of Writer.

fn enabled(&self, _: &Metadata<'_>) -> bool

fn make_writer_for(&'a self, _: &Metadata<'_>) -> Option<Self::Writer>

Returns a Writer for writing data from the span or event described by the provided Metadata.

fn line_len(&self) -> usize

impl PartialEq for NoWriter

fn eq(&self, other: &NoWriter) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl SetColor for NoWriter

fn set_fg_color(&mut self, _: Color)

fn fg_color(&self) -> Color

fn set_bold(&mut self, _: bool)

Sets bold text.

fn with_bold(&mut self) -> WithBold<'_, Self>

where Self: Write + Sized,

fn with_fg_color(&mut self, color: Color) -> WithFgColor<'_, Self>

where Self: Write + Sized,

impl Write for NoWriter

fn write_str(&mut self, _: &str) -> Result

Writes a string slice into this writer, returning whether the write succeeded.

fn write_fmt(&mut self, _: Arguments<'_>) -> Result

Glue for usage of the write! macro with implementors of this trait.

fn write_char(&mut self, c: char) -> Result<(), Error>

Writes a char into this writer, returning whether the write succeeded.
