FrameType

rama::http::proto::h3

Struct FrameType

pub struct FrameType(/* private fields */);

Available on crate features http and std only.

Expand description

The type of an HTTP/3 frame, sent as a variable-length integer (RFC 9114 §7.2).

Unknown frame types are preserved: a recipient of an unknown frame type on a stream that allows it “MUST ignore” the frame (RFC 9114 §9). The frame types that HTTP/2 assigned but HTTP/3 does not reuse are recognized separately via FrameType::is_h2_reserved because receiving them is a connection error of type H3_FRAME_UNEXPECTED (RFC 9114 §7.2.8).

Implementations§

impl FrameType

pub const DATA: FrameType

DATA (RFC 9114 §7.2.1).

pub const HEADERS: FrameType

pub const fn new(value: u64) -> FrameType

Construct a frame type from its raw value.

pub const fn value(self) -> u64

The raw frame-type value.

pub const fn is_reserved(self) -> bool

Whether this is a reserved type of the form 0x1f * N + 0x21 (RFC 9114 §7.2.8) used for greasing.

pub const fn is_h2_reserved(self) -> bool

Whether this frame type was assigned by HTTP/2 and has no HTTP/3 counterpart, so its receipt is a connection error of type H3_FRAME_UNEXPECTED (RFC 9114 §7.2.8): PRIORITY (0x02), PING (0x06), WINDOW_UPDATE (0x08), CONTINUATION (0x09).

pub const fn name(self) -> Option<&'static str>
