Struct WriteBuffer

pub struct WriteBuffer { /* private fields */ }

Available on crate feature alloc only.

A growable, nul-terminated UTF-8 buffer which implements fmt::Write.

Any nuls that are written to this are replaced with char::REPLACEMENT_CHARACTER. Allocation errors are exposed in fmt::writes.
