Struct Length

pub struct Length;

Combinator for the length field in a TLV tuple

Trait Implementations

impl Combinator for Length

type Result<'a> = usize

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

type Owned = usize

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 Debug for Length

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl SpecCombinator for Length

type SpecResult = usize

The view of Combinator::Result.

impl View for Length

type V = Length
