Trait lightning::util::ser::Writer

pub trait Writer {
    fn write_all(&mut self, buf: &[u8]) -> Result<(), Error>;
    fn size_hint(&mut self, size: usize);
}

A trait that is similar to std::io::Write but has one extra function which can be used to size buffers being written into. An impl is provided for any type that also impls std::io::Write which simply ignores size hints.

Required methods

fn write_all(&mut self, buf: &[u8]) -> Result<(), Error>

Writes the given buf out. See std::io::Write::write_all for more

fn size_hint(&mut self, size: usize)

Hints that data of the given size is about the be written. This may not always be called prior to data being written and may be safely ignored.
