fn write_to_fmt<W: Write>(&self, writer: W) -> Result

fn write_to_bytes<W: Write>(&self, writer: W) -> Result

fn format_with<F>(&self, f: F) -> Result

where F: FnMut(Option<&str>) -> Result,

Provided Methods

fn try_to_fmt<T: Write + Default>(&self) -> Result<T, T>

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
