Struct RepeatedView 

pub struct RepeatedView<B, T: HasView<B> + NextLayer> { /* private fields */ }

A borrowed block of headers whose elements are parsed identically (i.e., using the same choice or Ingot type), and may be chained using hint values.

Implementations

impl<B: ByteSlice, T: for<'a> HasView<&'a [u8]> + HasView<B> + NextLayer> RepeatedView<B, T>

pub fn iter(&self, hint: Option<T::Hint>) -> RepeatedViewIter<'_, T>

Iterates over all sub-parsed elements.

Offsets are not stored, so individual elements are re-parsed one by one.

Trait Implementations

impl<B: ByteSliceMut, T: HasView<B> + NextLayer> AsMut<[u8]> for RepeatedView<B, T>

fn as_mut(&mut self) -> &mut [u8]

Converts this type into a mutable reference of the (usually inferred) input type.

impl<B: ByteSlice, T: HasView<B> + NextLayer> AsRef<[u8]> for RepeatedView<B, T>

fn as_ref(&self) -> &[u8]

Converts this type into a shared reference of the (usually inferred) input type.

impl<B: ByteSlice, T: HeaderLen + NextLayer + HasView<B>> Emit for RepeatedView<B, T>

fn emit_raw<V: ByteSliceMut>(&self, buf: V) -> usize

Writes this packet’s contents into a target buffer without performing length checks.

fn needs_emit(&self) -> bool

Returns whether this packet needs a full re-emit, and has not been simply modified in-place.

fn emit<V: ByteSliceMut>(&self, buf: V) -> ParseResult<usize>

Writes this packet’s contents into a target buffer.

fn emit_prefix<V: SplitByteSliceMut>(&self, buf: V) -> ParseResult<V>

Writes this packet’s contents into the start of a target buffer.

fn emit_suffix<V: SplitByteSliceMut>(&self, buf: V) -> ParseResult<V>

Writes this packet’s contents at the end of a target buffer.

fn to_vec(&self) -> Vec<u8>

Writes this packet’s contents into a newly allocated Vec of length Header::packet_length.

impl<B: ByteSlice, T: HeaderLen + NextLayer + HasView<B>> HeaderLen for RepeatedView<B, T>

const MINIMUM_LENGTH: usize = 0usize

The minimum number of bytes a packet of this kind occupies when serialised.

fn packet_length(&self) -> usize

The number of bytes which this packet would occupy when serialised.

impl<B: SplitByteSlice, T> HeaderParse<B> for RepeatedView<B, T>

fn parse_choice(data: B, hint: Option<T::Hint>) -> ParseResult<Success<Self, B>>

Parse a view-type from a given buffer, using a hint

fn parse(from: B) -> ParseResult<Success<Self, B>>

Parse a view-type from a given buffer.

impl<B: ByteSlice, T: for<'a> HasView<&'a [u8]> + HasView<B> + NextLayer<Hint = <T as NextLayer>::Denom>> NextLayer for RepeatedView<B, T>

where for<'a> <T as HasView<&'a [u8]>>::ViewType: HeaderParse<&'a [u8]> + NextLayer<Denom = T::Denom, Hint = T::Hint>,

type Denom = <T as NextLayer>::Denom

The type of this header’s next-layer hint.

type Hint = <T as NextLayer>::Hint

A type used to help parse the header

fn next_layer_choice(&self, hint: Option<Self::Hint>) -> Option<Self::Denom>

Try to retrieve this header’s next-layer hint, using a provided hint

fn next_layer(&self) -> Option<Self::Denom>

Retrieve this header’s next-layer hint, if possible.

impl<B: SplitByteSlice, T, E> ToOwnedPacket for RepeatedView<B, T>

type Target = Repeated<T>

The output type of this conversion.

fn to_owned(&self, hint: Option<T::Hint>) -> ParseResult<Self::Target>

Converts a borrowed view of a header into an owned version, possibly reparsing to do so with the aid of hint.
