Struct ContextSnapshot 

pub struct ContextSnapshot { /* private fields */ }

Durable, verified context snapshot for storage adapters.

This is the supported rehydration boundary for embedders such as Helms. Storage persists this value and later calls ContextState::from_snapshot. It must not reconstruct facts through promotion constructors.

Implementations

impl ContextSnapshot

pub fn from_context(context: &ContextState) -> ContextSnapshot

Returns the context version captured by the snapshot.

pub fn merkle_root(&self) -> &MerkleRoot

Returns the snapshot Merkle root.

pub fn facts(&self) -> &BTreeMap<ContextKey, Vec<ContextFact>>

Returns fact projections grouped by context key.

pub fn proposals(&self) -> &BTreeMap<ContextKey, Vec<ProposedFact>>

Returns staged proposals grouped by context key.
