Trait fast_fmt::transform::Transform

pub trait Transform {
    fn transform_char<W: Write>(
        &self, 
        writer: &mut W, 
        c: char
    ) -> Result<(), W::Error>;
    fn transform_size_hint(&self, bytes: usize) -> usize;

    fn transform_str<W: Write>(
        &self, 
        writer: &mut W, 
        s: &str
    ) -> Result<(), W::Error> { ... }
}

Represents a transformation of text to another text.

It abstracts transforming a single value and a whole input to the writer.

Required Methods

fn transform_char<W: Write>(
    &self,
    writer: &mut W,
    c: char
) -> Result<(), W::Error>

Writes transformed char into provided writer.

fn transform_size_hint(&self, bytes: usize) -> usize

Calculates new size hint based on how transformation affects output size.

It should always be maximum of possible scenarios. If maximum can't be determined, the bytes value should be returned unchanged.

Provided Methods

fn transform_str<W: Write>(
    &self,
    writer: &mut W,
    s: &str
) -> Result<(), W::Error>

Writes transformed string into provided writer.
