Expand description

One bounded, invisible target record in a causal schema migration.

Implementations§

Source§

impl SchemaStage

Source

pub fn new( migration_id: MigrationId, from: SchemaDescriptor, to: SchemaDescriptor, source_record_id: Vec<u8>, source_digest: BlobHash, target_record: Vec<u8>, ) -> Result<SchemaStage, MigrationCodecError>

Validates and constructs one staged record.

Source

pub const fn migration_id(&self) -> MigrationId

Returns the migration identifier.

Source

pub const fn from(&self) -> &SchemaDescriptor

Returns the exact predecessor schema.

Source

pub const fn to(&self) -> &SchemaDescriptor

Returns the exact target schema.

Source

pub fn source_record_id(&self) -> &[u8] ⓘ

Returns the source record’s canonical primary key.

Source

pub const fn source_digest(&self) -> BlobHash

Returns the digest of the canonical source materialization.

Source

pub fn target_record(&self) -> &[u8] ⓘ

Returns the canonical target materialized-record bytes.

Source

pub fn encode_canonical(&self) -> Vec<u8> ⓘ

Encodes the stage into its unique durable representation.

Source

pub fn decode_canonical( bytes: &[u8], ) -> Result<SchemaStage, MigrationCodecError>

Strictly decodes one canonical stage.
