Available on crate features http and std only.

An instruction on the QPACK encoder stream (encoder → decoder, RFC 9204 §4.3).

Variants

SetDynamicTableCapacity

Set Dynamic Table Capacity (RFC 9204 §4.3.1).

Fields

capacity: u64

The new maximum table capacity in bytes.

InsertWithNameRef

Insert with Name Reference (RFC 9204 §4.3.2): a new entry whose name is an existing entry.

Fields

is_static: bool

Whether the name index is static (T=1) or dynamic (T=0, relative index).

name_index: u64

The static index, or the relative dynamic index of the name.

value: Bytes

The literal value.

value_huffman: bool

Whether the value was Huffman-encoded on the wire.

InsertWithLiteralName

Insert with Literal Name (RFC 9204 §4.3.3): a new entry with a literal name and value.

Fields

name: Bytes

The literal name.

name_huffman: bool

Whether the name was Huffman-encoded on the wire.

value: Bytes

The literal value.

value_huffman: bool

Whether the value was Huffman-encoded on the wire.

Duplicate

Duplicate (RFC 9204 §4.3.4): re-insert an existing entry (e.g. to avoid eviction).

Fields

index: u64

The relative index of the entry to duplicate.

Implementations

impl EncoderInstruction

pub fn encode<B>(&self, dst: &mut B)

where B: BufMut,

Encode this instruction into dst.

pub fn decode( src: &mut &[u8], max_string_len: usize, ) -> Result<EncoderInstruction, PrefixError>

Decode one encoder-stream instruction, bounding each decoded string by max_string_len.

pub fn decode_bytes( src: &mut Bytes, max_string_len: usize, ) -> Result<EncoderInstruction, PrefixError>

Decode from owned bytes, slicing plain literals without copying their payloads. Leaves the cursor unchanged on error.

pub fn encoded_len( src: &[u8], max_string_len: usize, ) -> Result<usize, PrefixError>

Probe the complete instruction length without decoding or allocating strings. Incomplete bodies return UnexpectedEnd; impossible string lengths fail early.

Trait Implementations

impl Clone for EncoderInstruction

fn clone(&self) -> EncoderInstruction

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for EncoderInstruction

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

Formats the value using the given formatter.

impl Eq for EncoderInstruction

impl PartialEq for EncoderInstruction

fn eq(&self, other: &EncoderInstruction) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
