Enum QuicVersion 

#[non_exhaustive]
pub enum QuicVersion {
    V1,
    V2,
    Draft(u8),
    Other(u32),
}

Available on crate feature quic only.

QUIC version, decoded from the long-header version field. RFC-named versions get dedicated variants; IETF drafts and unknowns preserve the raw u32 for forensics.

Why a typed enum: routing decisions on “is this RFC 9000 v1 traffic vs RFC 9369 v2 vs a draft” are stronger than version == 0x00000001 magic-number checks at consumer call sites.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

V1

QUIC v1 — RFC 9000 (0x00000001).

V2

QUIC v2 — RFC 9369 (0x6b3343cf).

Draft(u8)

IETF draft version (0xff000000..=0xff00007f). Carries the draft number (raw & 0xFF).

Other(u32)

Any other version. Raw u32 preserved.

Implementations
