Struct fast_fmt::transform::Transformer

pub struct Transformer<T: Transform, W: Write> { /* fields omitted */ }

Transformation attached to a writer, transforming everything written into the writer.

Methods

impl<T: Transform, W: Write> Transformer<T, W>

fn new(transformation: T, writer: W) -> Self

Attaches transformation to the writer.

Trait Implementations

impl<T: Transform, W: Write> Write for Transformer<T, W>

type Error = W::Error

Type of error returned if write fails.

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

Writes single char.

fn write_str(&mut self, s: &str) -> Result<(), Self::Error>

Writes whole string.

fn size_hint(&mut self, bytes: usize)

Hints that implementor should allocate enough space so that string containing bytes UTF-8 bytes can be stored in it.

fn uses_size_hint(&self) -> bool

Tells the user whether the size hint is actually used. This allows the user to skip calculation of the hint.

fn transform<T: Transform>(self, transformation: T) -> Transformer<T, Self> where
    Self: Sized, 

Combinator for creating transformed writer.
