Enum Ecn 

pub enum Ecn {
    NotEct,
    Ect1,
    Ect0,
    Ce,
}

Explicit Congestion Notification codepoint.

Represents the 2-bit ECN field in the IP header (ToS for IPv4, Traffic Class for IPv6).

See RFC 9331 for the use of ECN with QUIC and RFC 3168 for the original specification.

Variants

NotEct

Not ECN-Capable Transport — routers may drop the packet on congestion.

Ect1

ECN-Capable Transport, codepoint 1.

Ect0

ECN-Capable Transport, codepoint 0.

Ce

Congestion Experienced — set by a router on an ECT-marked packet.

Implementations

impl Ecn

pub fn to_tos_bits(self) -> u8

Encode the ECN codepoint as the low 2 bits of a TOS/Traffic Class byte.

pub fn from_tos_bits(tos: u8) -> Self

Decode the ECN codepoint from the low 2 bits of a TOS/Traffic Class byte.
