pub fn with<F: FnOnce(Arguments) -> R, R>(&self, f: F) -> R

Call a function accepting Arguments with the contents of this buffer.

pub fn format(&self) -> String

Format this buffer to a String.

pub fn print(&self)

pub fn write_io<W: Write + ?Sized>(&self, dest: &mut W) -> Result<()>

Write this buffer to an io::Write.

pub fn write_fmt<W: Write + ?Sized>(&self, dest: &mut W) -> Result

Write this buffer to a fmt::Write.
