Validates and constructs an activation marker.

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 const fn staged_records(&self) -> u64

Returns the exact number of selected stage records.

Source

pub const fn staging_digest(&self) -> BlobHash

Returns the digest committing to the complete ordered staging set.

Source

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

Encodes the activation into its unique durable representation.

Source

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

Strictly decodes one canonical activation.
