Struct SchemaActivation 

pub struct SchemaActivation { /* private fields */ }

The atomic publication marker for a complete staged migration.

Implementations

impl SchemaActivation

pub fn new( migration_id: MigrationId, from: SchemaDescriptor, to: SchemaDescriptor, staged_records: u64, staging_digest: BlobHash, ) -> Result<Self, MigrationCodecError>

Validates and constructs an activation marker.

pub const fn migration_id(&self) -> MigrationId

Returns the migration identifier.

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

Returns the exact predecessor schema.

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

Returns the exact target schema.

pub const fn staged_records(&self) -> u64

Returns the exact number of selected stage records.

pub const fn staging_digest(&self) -> BlobHash

Returns the digest committing to the complete ordered staging set.

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

Encodes the activation into its unique durable representation.

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

Strictly decodes one canonical activation.

Trait Implementations

impl Clone for SchemaActivation

fn clone(&self) -> SchemaActivation

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SchemaActivation

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for SchemaActivation

fn eq(&self, other: &SchemaActivation) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
