Expand description

Header frame

This could be either a request or a response.

Fields§

§stream_id: StreamId

§flags: HeadersFlag

The associated flags

Implementations§

source§

impl Headers

source

pub fn new(stream_id: StreamId, pseudo: Pseudo, fields: HeaderMap) -> Self

Create a new HEADERS frame

source

pub fn trailers(stream_id: StreamId, fields: HeaderMap) -> Self

source

pub fn load(head: Head, src: BytesMut) -> Result<(Self, BytesMut), Error>

Loads the header frame but doesn’t actually do HPACK decoding.

HPACK decoding is done in the load_hpack step.

source

pub fn load_hpack( &mut self, src: &mut BytesMut, max_header_list_size: usize, decoder: &mut Decoder ) -> Result<(), Error>

source

pub fn stream_id(&self) -> StreamId

source

pub fn is_end_headers(&self) -> bool

source

pub fn set_end_headers(&mut self)

source

pub fn is_end_stream(&self) -> bool

source

pub fn set_end_stream(&mut self)

source

pub fn is_over_size(&self) -> bool

source

pub fn into_parts(self) -> (Pseudo, HeaderMap)

source

pub(crate) fn is_informational(&self) -> bool

Whether it has status 1xx

source

pub fn fields(&self) -> &HeaderMap

source

pub fn into_fields(self) -> HeaderMap

source

pub fn encode( self, encoder: &mut Encoder, dst: &mut Limit<&'_ mut BytesMut> ) -> Option<Continuation>

source

Trait Implementations§

impl<T> From<Headers> for Frame<T>

source§

fn from(src: Headers) -> Self

Converts to this type from the input type.
source§

impl PartialEq<Headers> for Headers

source§

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

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
