Struct HpackDecoder 

pub struct HpackDecoder { /* private fields */ }

A connection-direction HPACK decoder with bounded table and header-list sizes.

Implementations

impl HpackDecoder

pub fn new(max_table_size: usize, max_header_list_size: usize) -> HpackDecoder

Creates a decoder with explicit dynamic table and decoded list limits. Each decoded field contributes its name and value octets plus 32 bytes.

Errors

This function does not return errors.

Panics

This function does not panic.

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

Changes the permitted table limit after the peer acknowledges SETTINGS. A reduction requires a matching update at the next header block’s start.

Errors

This function does not return errors.

Panics

This function does not panic.

pub fn decode( &mut self, block: &[u8], ) -> Result<Vec<(String, String)>, ProtoError>

Decodes one complete header block, preserving order and duplicate fields. A list-size rejection still processes valid table changes through the end of the block, allowing later streams to reuse the compression context. Names and values must be UTF-8 because this API exposes Rust strings. A compression error permanently rejects later blocks because the peer’s table state can no longer be recovered from the malformed block.

Errors

Returns ProtoError::Hpack for malformed representations, invalid table references, integer overflow, invalid UTF-8, missing required updates, or a compression context that previously failed. Returns ProtoError::HeaderListTooLarge if the decoded list exceeds its limit.

Panics

This function does not panic.

Trait Implementations

impl Debug for HpackDecoder

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

impl Default for HpackDecoder

fn default() -> HpackDecoder

Returns the “default value” for a type.
