Struct Http2Frame 

pub struct Http2Frame {
    pub length: u32,
    pub frame_type: Http2FrameType,
    pub flags: u8,
    pub stream_id: u32,
    pub payload_offset: usize,
    pub total_size: usize,
}

A parsed HTTP/2 frame, holding the frame header fields and a reference to where the payload resides in the original buffer.

Fields

length: u32

24-bit payload length.

frame_type: Http2FrameType

Frame type.

flags: u8

Flags byte.

stream_id: u32

31-bit stream identifier (R bit masked out).

payload_offset: usize

Byte offset in the original buffer where the payload starts.

total_size: usize

Total frame size in bytes: 9 (header) + payload length.

Implementations

impl Http2Frame

pub fn parse_at(buf: &[u8], offset: usize) -> Option<Self>

Parse one HTTP/2 frame from buf starting at offset.

Returns None if there are not enough bytes for the frame header or if the payload extends beyond the buffer.

pub fn payload<'a>(&self, buf: &'a [u8]) -> &'a [u8]

Get the payload bytes from the original buffer.

pub fn is_end_stream(&self) -> bool

Returns true if the END_STREAM flag is set.

Valid for DATA and HEADERS frames.

pub fn is_end_headers(&self) -> bool

Returns true if the END_HEADERS flag is set.

Valid for HEADERS, PUSH_PROMISE, and CONTINUATION frames.

pub fn is_ack(&self) -> bool

Returns true if the ACK flag is set.

Valid for SETTINGS and PING frames.

pub fn is_padded(&self) -> bool

Returns true if the PADDED flag is set.

Valid for DATA, HEADERS, and PUSH_PROMISE frames.

pub fn has_priority(&self) -> bool

Returns true if the PRIORITY flag is set.

Valid for HEADERS frames.

pub fn summary(&self) -> String

Get a human-readable summary of this frame.

Trait Implementations

impl Clone for Http2Frame

fn clone(&self) -> Http2Frame

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Http2Frame

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