Struct Encoder 

pub struct Encoder { /* private fields */ }

Available on crate feature h2 and (crate features h2 or h3) only.

Encodes HPACK header blocks.

Implementations

impl Encoder

pub fn new(max_table_size: usize) -> Self

Creates an encoder whose table allows max_table_size octets (RFC 7541 Section 4.2: 4096 by default). This must match the peer’s initial SETTINGS_HEADER_TABLE_SIZE.

pub fn queue_size_update(&mut self, size: usize)

Queues a protocol-level table size update (from SETTINGS) to be applied and emitted at the start of the next header block.

pub fn set_use_huffman(&mut self, use_huffman: bool)

Controls Huffman-coded string literals. Enabled by default, in which case a literal is Huffman-coded when that is shorter.

pub fn encode(&mut self, headers: &[Header], out: &mut Vec<u8>)

Encodes headers as a single header block appended to out.

Non-sensitive headers are encoded with incremental indexing (RFC 7541 Section 6.2.1) and added to the dynamic table; exact matches use the indexed representation (Section 6.1). Sensitive headers ([NEVER_INDEXED]) are encoded never-indexed (Section 6.2.3) and never added to the table.

Trait Implementations

impl Debug for Encoder

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

Formats the value using the given formatter.
