StreamType

rama::http::proto::h3

Struct StreamType

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

Available on crate features http and std only.

Expand description

The type of an HTTP/3 unidirectional stream, sent as a variable-length integer at the start of the stream (RFC 9114 §6.2).

Unknown stream types are preserved rather than rejected so that the abort/skip policy (RFC 9114 §6.2, where a recipient of an unknown stream type must not treat it as an error) can be applied by the connection layer. Reserved (0x1f * N + 0x21) types are used for greasing.

Implementations§

impl StreamType

pub const CONTROL: StreamType
