Struct Tag

pub struct Tag<Inner, T>(pub Refined<Inner, TagPred<T>>);

Generic tag combinator that matches the input with a given value and discards it e.g. Tag(Int::<u8>, 0) matches the byte 0; Tag(Bytes::<3>, &[1, 2, 3]) matches the bytes [1, 2, 3]

Tuple Fields

0: Refined<Inner, TagPred<T>>

Implementations

impl<Inner, T> Tag<Inner, T>

impl<'a, Inner> Combinator for Tag<Inner, &'a [u8]>

where Inner: for<'b> Combinator<Result<'b> = &'b [u8], Owned = Vec<u8>>, <Inner as View>::V: SecureSpecCombinator<SpecResult = Seq<u8>>,

type Result<'b> = ()

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

type Owned = ()

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.
