Struct FrameHeader 

pub struct FrameHeader {
    pub frame: u32,
    pub width: u16,
    pub height: u16,
    pub format: FrameFormat,
    pub len: u32,
}

16-byte little-endian header of a binary WS frame:

bytes	field
0..4	frame
4..6	width
6..8	height
8	format
9..12	reserved, zero
12..16	len of the body that follows

Fields

frame: u32

Global frame index.

width: u16

Image width in pixels.

height: u16

Image height in pixels.

format: FrameFormat

Encoding of the body.

len: u32

Body length in bytes.

Implementations

impl FrameHeader

pub const SIZE: usize = 16

Header length in bytes.

pub fn encode(&self) -> [u8; 16]

Serializes the header.

pub fn decode(bytes: &[u8]) -> Option<Self>

Parses a header from the start of bytes; None if too short or unknown format.
