Struct WriteBuf

pub struct WriteBuf { /* private fields */ }

Implementations

impl WriteBuf

pub fn new() -> WriteBuf

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

pub fn into_inner(self) -> BytesMut

pub fn clear(&mut self)

clear remaining bytes in buffer and set flush flag to false. this would make following BufInterest::want_write_io call return false.

pub fn buf(&self) -> &[u8]

Trait Implementations

impl BufInterest for WriteBuf

fn want_write_buf(&self) -> bool

flag if buffer want more data to be filled in.

fn want_write_io(&self) -> bool

flag if buffer want to write data to io.

impl BufWrite for WriteBuf

fn write_buf<F, T, E>(&mut self, func: F) -> Result<T, E>

where F: FnOnce(&mut BytesMut) -> Result<T, E>,

write into BytesMut with closure that output a Result type. the result type is used to hint buffer to stop wanting to flush IO on BufWrite::do_io or revert BytesMut to previous state before method was called.

fn do_io<Io>(&mut self, io: &mut Io) -> Result<(), Error>

where Io: Write,

write into IO from buffer.

impl Default for WriteBuf

fn default() -> WriteBuf

Returns the “default value” for a type.
