Struct PeerCapabilitySet 

pub struct PeerCapabilitySet {
    pub peer_id: String,
    pub capabilities: HashSet<PeerCapability>,
    pub version: String,
    pub advertised_at: u64,
    pub last_verified: Option<u64>,
}

The full capability advertisement for a single remote peer.

This is the unit stored inside CapabilityRegistry. The advertised_at field carries a Unix-epoch millisecond timestamp which is compared against the registry’s ttl_ms to determine freshness.

Fields

peer_id: String

Unique peer identifier (string form of the libp2p PeerId).

capabilities: HashSet<PeerCapability>

Set of capabilities this peer claims to support.

version: String

Peer’s self-reported IPFRS protocol version string, e.g. "0.2.0".

advertised_at: u64

Unix-epoch millisecond timestamp when this record was first advertised.

last_verified: Option<u64>

Unix-epoch millisecond timestamp of the most recent successful verification, if any.

Implementations

impl PeerCapabilitySet

pub fn has(&self, cap: &PeerCapability) -> bool

Returns true if this peer supports cap.

pub fn has_all(&self, caps: &[PeerCapability]) -> bool

Returns true if this peer supports all capabilities in caps.

pub fn has_any(&self, caps: &[PeerCapability]) -> bool

Returns true if this peer supports at least one capability in caps. Returns true when caps is empty (vacuous truth).

pub fn is_expired(&self, now_ms: u64, ttl_ms: u64) -> bool

Returns true if the record has expired given now_ms and ttl_ms.

Expiry is defined as now_ms >= advertised_at + ttl_ms.

Trait Implementations

impl Clone for PeerCapabilitySet

fn clone(&self) -> PeerCapabilitySet

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for PeerCapabilitySet

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
