Trait Implementations

impl Combinator for Fail

type Result<'a> = ()

The result type of parsing and the input type of serialization.

type Owned = ()

The owned parsed type. This is currently a hack to avoid lifetime bindings in SpecCombinator::SpecResult , but it can be useful if we want to have functions that return owned values (e.g. Vec<T>).

fn length(&self) -> Option<usize>

The length of the output buffer, if known. This can be used to optimize serialization by pre-allocating the buffer.

fn parse<'a>( &self, _s: &'a [u8], ) -> Result<(usize, <Fail as Combinator>::Result<'a>), ParseError>

The parsing function.

fn serialize( &self, _v: <Fail as Combinator>::Result<'_>, _data: &mut Vec<u8>, _pos: usize, ) -> Result<usize, SerializeError>

The serialization function.

impl SpecCombinator for Fail

type SpecResult = ()

The view of Combinator::Result.
