Struct Decoder 

pub struct Decoder { /* private fields */ }

A stateful header block decoder.

Implementations

impl Decoder

pub fn new(max_table_size: usize, max_list_size: usize) -> Self

A decoder whose dynamic table may grow to max_table_size (the value advertised in SETTINGS_HEADER_TABLE_SIZE) and whose decoded header lists are capped at max_list_size.

pub fn set_max_allowed(&mut self, max: usize)

Changes the largest table size the peer may select (after our new SETTINGS were acknowledged). A smaller value shrinks the table at once.

pub fn set_max_list_size(&mut self, max: usize)

Changes the header list cap.

pub fn table_size(&self) -> usize

Current dynamic table size in octets (RFC 7541 §4.1).

pub fn table_max_size(&self) -> usize

Current dynamic table maximum (the last size update).

pub fn table_len(&self) -> usize

Number of dynamic table entries.

pub fn table_entry(&self, i: usize) -> Option<(&[u8], &[u8])>

Dynamic table entry i (0 = newest).

pub fn decode( &mut self, block: &[u8], emit: &mut dyn FnMut(&[u8], &[u8]), ) -> Result<(), Error>

Decodes one complete header block, passing each field (name, value) to emit in order.

When the list grows past the cap the rest of the block is still decoded, to keep the dynamic table in step, but not emitted, and Error::HeaderListTooLarge is returned.

Trait Implementations

impl Clone for Decoder

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Decoder

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

Formats the value using the given formatter.
