Trait Implementations

impl Capability for AaeTreeFormat

type Value = u32

The typed value this capability negotiates.

fn name(&self) -> &'static str

Stable on-the-wire name. Must be ASCII.

fn supported_values(&self) -> Vec<u32>

Locally supported values, ordered from lowest preference to highest preference. The first element is also used as the “floor” when negotiation finds no overlap.

fn merge(&self, peer: &[u32]) -> Option<u32>

Returns the highest local value also supported by peer, or None when there is no overlap. The notion of “highest” is owned by the implementation.

fn encode_value(&self, v: &u32) -> Vec<u8>

Serialise a value to a stable byte sequence. Used to build the on-the-wire advertisement.

fn decode_value(&self, b: &[u8]) -> Option<u32>

Inverse of Capability::encode_value. Returning None causes the registry to drop the malformed value when merging a peer ad.
