Struct CapabilityNegotiation 

pub struct CapabilityNegotiation {
    pub schema: String,
    pub features: BTreeMap<String, bool>,
}

Peer-advertised protocol feature bitset.

The map is intentionally string-keyed so new additive features can be introduced without a flag-day enum release. Validation still rejects malformed names fail-closed before any negotiated feature is used.

Fields

schema: String

features: BTreeMap<String, bool>

Implementations

impl CapabilityNegotiation

pub fn v1_default() -> CapabilityNegotiation

Baseline peer profile: v1 capability tokens only.

pub fn t1_default() -> CapabilityNegotiation

T1 peer profile: current capability semantics and anchor batches.

The DELEGATION_CHAIN_BINDING flag is advertised as true so production peers exercise the chain-binding check by default. Peers that need to interoperate with a counterparty that has not rolled out chain-binding can explicitly clear the flag in the intersected profile, but the safe direction is to leave it on.

pub fn supports(&self, feature: &str) -> bool

Return whether a named feature is explicitly advertised.

pub fn validate(&self) -> Result<(), Error>

Validate schema and feature-name shape before negotiation.

pub fn negotiated_with( &self, remote: &CapabilityNegotiation, ) -> Result<CapabilityNegotiation, Error>

Intersect two negotiated feature sets.
