[−][src]Struct bytecodec::combinator::Omittable
Combinator for representing optional decoders.
This is created by calling DecodeExt::omit method.
Methods
impl<D> Omittable<D>[src]
pub fn inner_ref(&self) -> &D[src]
Returns a reference to the inner decoder.
pub fn inner_mut(&mut self) -> &mut D[src]
Returns a mutable reference to the inner decoder.
pub fn into_inner(self) -> D[src]
Takes ownership of this instance and returns the inner decoder.
pub fn do_omit(&mut self, b: bool)[src]
If true is specified, the decoder will consume no bytes and
return Ok((0, None)) when decode method is called.
pub fn will_omit(&self) -> bool[src]
Returns true if the decoder will omit to decode items, otherwise false.
