Enum CommitteeResolution 

#[non_exhaustive]
pub enum CommitteeResolution {
    TrustedNode,
    Anchored {
        committee: Committee,
        chain_identifier: Option<ChainIdentifier>,
        cache: Arc<dyn CommitteeCache>,
    },
}

Selects how a resolver establishes trust in committee data.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

TrustedNode

Accept committee data returned directly by the connected node.

This does not authenticate committee lineage. Use it only when the node is inside the caller’s trust boundary.

Anchored

Authenticate committee lineage from an existing trust anchor.

Fields

committee: Committee

First committee trusted by the caller.

chain_identifier: Option<ChainIdentifier>

Trusted network identity used to namespace a shared cache, or None when the cache is private to this resolution.

cache: Arc<dyn CommitteeCache>

Cache containing authenticated successor committees.

Implementations

impl CommitteeResolution

pub fn anchored(committee: Committee) -> Self

Anchors committee resolution at an already trusted committee.

Authenticated committees are retained in a fresh in-memory cache.

pub fn anchored_with_cache( chain_identifier: ChainIdentifier, committee: Committee, cache: impl CommitteeCache + 'static, ) -> Self

Anchors committee resolution using a caller-provided committee cache.

chain_identifier must be the trusted genesis checkpoint digest for the network containing committee. It namespaces entries in the shared cache.

pub fn from_genesis(reader: impl Read) -> Result<Self, CommitteeResolutionError>

Anchors committee resolution at the committee contained in a trusted genesis blob.

The reader must contain the BCS-encoded genesis.blob for the proof’s network. Authenticated committees are retained in a fresh in-memory cache.

pub fn from_genesis_with_cache( reader: impl Read, cache: impl CommitteeCache + 'static, ) -> Result<Self, CommitteeResolutionError>

Anchors committee resolution from a trusted genesis blob using a caller-provided cache.

The reader must contain the BCS-encoded genesis.blob for the proof’s network. Cache entries are scoped automatically to the genesis checkpoint digest.
