Trait writeable::Writeable

pub trait Writeable {
    fn write_to(&self, sink: &mut dyn Write) -> Result;
    fn write_len(&self) -> usize;

    fn writeable_to_string(&self) -> String { ... }
}

Writeable is an alternative to std::fmt::Display with the addition of a length function.

Required methods

fn write_to(&self, sink: &mut dyn Write) -> Result

Writes bytes to the given sink. Errors from the sink are bubbled up.

fn write_len(&self) -> usize

Returns an estimation of the number of bytes that will be written to the sink. The actual number of bytes may be slightly different than what this function returns.

This function may return an enumeration in the future. See: https://github.com/unicode-org/icu4x/issues/370
