SettingId

Struct SettingId

pub struct SettingId(pub u64);

Expand description

An HTTP/3 setting identifier.

Used in SETTINGS frames to configure connection parameters. Standard identifiers are available as associated constants (e.g. SettingId::QPACK_MAX_TABLE_CAPACITY).

Tuple Fields§

§0: u64

Implementations§

impl SettingId

pub fn grease() -> Self

Returns a SettingId with a random number of the 0x1f * N + 0x21 format. The multiplier N is bounded to a u32, matching Chromium’s GREASE setting ID generation.

impl SettingId

pub const QPACK_MAX_TABLE_CAPACITY: SettingId

SETTINGS_QPACK_MAX_TABLE_CAPACITY from RFC 9204 Section 5.

pub const QPACK_MAX_BLOCKED_STREAMS: SettingId

SETTINGS_QPACK_BLOCKED_STREAMS from RFC 9204 Section 5.

pub const MAX_HEADER_LIST_SIZE: SettingId

SETTINGS_MAX_FIELD_SECTION_SIZE from RFC 9114 Section 7.2.4.1.

The associated constant keeps its historical HTTP/2 name for API compatibility; HTTP/3 renamed the setting without changing code point 0x06.
