Struct TypedVersionedMap 

pub struct TypedVersionedMap<'a, S: Store, K, V, KC, VC> { /* private fields */ }

Typed facade over a byte-oriented VersionedMap.

Implementations

impl<'a, S: Store, K, V, KC, VC> TypedVersionedMap<'a, S, K, V, KC, VC>

pub fn raw(&self) -> &VersionedMap<'a, S>

Borrow the byte-oriented managed map.

impl<S, K, V, KC, VC> TypedVersionedMap<'_, S, K, V, KC, VC>

where S: Store + ManifestStore, V: DeserializeOwned, KC: KeyCodec<K>, VC: ValueCodec,

pub fn get(&self, key: &K) -> Result<Option<V>, Error>

Read and schema-validate one typed value from head.

pub fn get_at(&self, id: &MapVersionId, key: &K) -> Result<Option<V>, Error>

Read and schema-validate one typed value from a historical version.

pub fn entries(&self) -> Result<Vec<(K, V)>, Error>

Decode all entries in key order.

impl<S, K, V, KC, VC> TypedVersionedMap<'_, S, K, V, KC, VC>

where S: Store + ManifestStore + TransactionalStore, V: Serialize, KC: KeyCodec<K>, VC: ValueCodec,

pub fn put(&self, key: &K, value: &V) -> Result<MapVersion, Error>

Encode and publish one typed value.

pub fn put_if( &self, expected: Option<&MapVersionId>, key: &K, value: &V, ) -> Result<VersionedMapUpdate, Error>

Conditionally encode and publish one typed value.

pub fn delete(&self, key: &K) -> Result<MapVersion, Error>

Delete one typed key.

pub fn migrate_from<Old, OVC>( &self, expected: &MapVersionId, source_codec: &OVC, migrate: impl FnMut(Old) -> Result<V, Error>, ) -> Result<TypedMigrationResult, Error>

where Old: DeserializeOwned, OVC: ValueCodec,

Rewrite every value from source_codec through migrate and CAS-publish.
