Struct Participant 

pub struct Participant { /* private fields */ }

A participant in a coordinated action.

Implementations

impl Participant

pub fn new( agent: PublicKey, role: ParticipantRole, responsibility: Responsibility, commitment: Sig, ) -> Self

Create a new participant.

pub fn with_commitment( agent: PublicKey, role: ParticipantRole, responsibility: Responsibility, commitment: Sig, ) -> Self

Create a new participant with a commitment signature.

This is the preferred constructor. The commitment should be a signature over the CoordinatedActionSpec::canonical_bytes() using the agent’s secret key, per INV-COORD-2.

pub fn with_capabilities(self, capabilities: Vec<CapabilityId>) -> Self

Add capabilities.

pub fn agent(&self) -> &PublicKey

Get the agent.

pub fn role(&self) -> &ParticipantRole

Get the role.

pub fn capabilities(&self) -> &[CapabilityId]

Get the capabilities.

pub fn responsibility(&self) -> &Responsibility

Get the responsibility.

pub fn commitment(&self) -> &Sig

Get the commitment signature.

pub fn is_coordinator(&self) -> bool

Check if this participant is the coordinator.

pub fn verify_commitment(&self, spec: &CoordinatedActionSpec) -> Result<()>

Verify that this participant’s commitment is a valid signature over the given action specification, using the participant’s own agent key.

Enforces INV-COORD-2: every participant’s commitment must cryptographically verify against the coordination’s action specification.
