Struct FrameWriter 

pub struct FrameWriter {
    pub max_frame_size: usize,
}

Available on crate feature h2 only.

Writes frames to an output buffer. The field-block writer (FrameWriter::write_field_block) splits the block across HEADERS/CONTINUATION frames at the peer’s frame-size limit.

Fields

max_frame_size: usize

The maximum payload size the peer accepts (the peer’s SETTINGS_MAX_FRAME_SIZE; 16384 by default).

Implementations

impl FrameWriter

pub const fn new(max_frame_size: usize) -> FrameWriter

pub fn write_data( &self, out: &mut Vec<u8>, stream_id: u32, end_stream: bool, data: &[u8], )

pub fn write_headers( &self, out: &mut Vec<u8>, stream_id: u32, end_stream: bool, end_headers: bool, priority: Option<Priority>, block: &[u8], )

Writes a HEADERS frame (single frame, no field-block splitting).

pub fn write_field_block( &self, out: &mut Vec<u8>, stream_id: u32, end_stream: bool, block: &[u8], )

Writes a field block as a HEADERS frame (optionally with END_STREAM) followed by as many CONTINUATION frames as needed to stay within the peer’s frame-size limit.

pub fn write_priority( &self, out: &mut Vec<u8>, stream_id: u32, priority: Priority, )

pub fn write_reset(&self, out: &mut Vec<u8>, stream_id: u32, error_code: u32)

pub fn write_settings(&self, out: &mut Vec<u8>, settings: &[Setting])

pub fn write_settings_ack(&self, out: &mut Vec<u8>)

pub fn write_push_promise( &self, out: &mut Vec<u8>, stream_id: u32, promised_stream_id: u32, block: &[u8], )

pub fn write_ping(&self, out: &mut Vec<u8>, payload: &[u8; 8])

pub fn write_ping_ack(&self, out: &mut Vec<u8>, payload: &[u8; 8])

pub fn write_goaway( &self, out: &mut Vec<u8>, last_stream_id: u32, error_code: u32, debug: &[u8], )

pub fn write_window_update( &self, out: &mut Vec<u8>, stream_id: u32, increment: u32, )

pub fn write_continuation( &self, out: &mut Vec<u8>, stream_id: u32, end_headers: bool, block: &[u8], )
