Struct Cached

pub struct Cached<T>(pub T);

Same behavior as T, but also returns the slice consumed by T in the exec version

Tuple Fields

0: T

Trait Implementations

impl<T: Combinator> Combinator for Cached<T>

where T::V: SecureSpecCombinator<SpecResult = <T::Owned as View>::V>,

type Result<'a> = CachedValue<'a, T>

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

type Owned = <T as Combinator>::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, Self::Result<'a>), ParseError>

The parsing function.

fn serialize( &self, v: Self::Result<'_>, data: &mut Vec<u8>, pos: usize, ) -> Result<usize, SerializeError>

The serialization function.

impl<T: SpecCombinator> SpecCombinator for Cached<T>

type SpecResult = <T as SpecCombinator>::SpecResult

The view of Combinator::Result.

impl<T: View> View for Cached<T>

type V = Cached<<T as View>::V>
