ValidationCache

Struct ValidationCache 

Source
pub struct ValidationCache { /* private fields */ }
Expand description

Successful-program validation cache shared by concrete drivers.

Implementations§

Source§

impl ValidationCache

Source

pub fn new( max_hash_entries: usize, max_vsa_entries: usize, vsa_shards: usize, ) -> Self

Create a validation cache with bounded hash and VSA storage.

Source

pub fn program_hash(program: &Program) -> Hash

Compute the validation hash for a program.

Source

pub fn contains_hash(&self, hash: &Hash) -> bool

Return whether a validation hash is cached.

Source

pub fn remember_hash(&self, hash: Hash)

Remember a successful validation hash.

Source

pub fn remember_success( &self, hash: Hash, vsa: &[u32], ) -> Result<(), BackendError>

Remember a successful validation hash and its VSA fingerprint.

§Errors

Returns if a VSA shard lock is poisoned.

Source

pub fn clear(&self) -> Result<(), BackendError>

Clear cached validation state.

§Errors

Returns if a VSA shard lock is poisoned.

Source

pub fn get_or_validate( &self, program: &Program, validation_options: ValidationOptions<'_>, supported_ops: &HashSet<OpId>, caps: ProgramValidationCaps, ) -> Result<(), BackendError>

Validate program once, memoizing the complete backend contract.

This is the shared driver validation path: foundation invariants, backend supported-op coverage, program capability requirements, and VSA cache insertion all happen in one place. Concrete drivers supply only their actual capability values.

§Errors

Returns when validation fails or a VSA shard lock is poisoned.

Source

pub fn get_or_validate_backend<B>( &self, program: &Program, backend: &B, ) -> Result<(), BackendError>

Validate program against a concrete backend and cache successful results.

This is the canonical driver-owned validation-cache entry point for backends that implement both the runtime backend contract and the foundation capability-validation contract.

§Errors

Returns when validation fails or cache mutation fails.
