Struct SharedCommittees 

pub struct SharedCommittees { /* private fields */ }

Process-global, append-only cache of committees by epoch.

Committees are network-global state (created by the admin chain, agreed on by every validator), so caching them once per process avoids holding a separate copy in every chain’s execution state. The map is populated lazily by get_or_load-style lookups in crate::ExecutionRuntimeContext and in the storage layer.

Implementations

impl SharedCommittees

pub fn new() -> Self

pub fn get(&self, epoch: Epoch) -> Option<Arc<Committee>>

Returns the cached committee for epoch, if any.

pub fn insert(&self, epoch: Epoch, committee: Arc<Committee>) -> Arc<Committee>

Inserts committee for epoch. If an entry was already present, the existing value wins and is returned (avoiding spurious clones when two callers race to populate the same epoch).
