Struct FrameHeader 

pub struct FrameHeader {
    pub ty: FrameType,
    pub len: u64,
}

Available on crate features http and std only.

The header of an HTTP/3 frame: a type followed by the byte length of its payload (RFC 9114 §7.1). It carries no payload; the payload is decoded by the layer that owns the frame body.

Fields

ty: FrameType

The frame type.

len: u64

The payload length in bytes.

Implementations

impl FrameHeader

pub const fn new(ty: FrameType, len: u64) -> FrameHeader

Construct a frame header.

pub fn wire_len(&self) -> Option<usize>

The number of bytes this header occupies once encoded.

Returns None if either the type or the length is not a valid variable-length integer.

pub fn encode<B>(&self, dst: &mut B) -> Option<()>

where B: BufMut,

Encode this header into dst.

Returns None without writing anything if the type or length exceeds the variable-length integer range.
