Struct PersistedMigrationCheckpoint 

pub struct PersistedMigrationCheckpoint {
    pub migration_id: String,
    pub attempt: u32,
    pub payload: MigrationCheckpointPayload,
    pub crc32c: u32,
    pub ts_ms: u64,
}

The value stored in the MIGRATION_STATE_TABLE redb table.

One row per MigrationId; upserted on every committed MigrationCheckpoint and deleted when MigrationAbort applies.

Fields

migration_id: String

attempt: u32

payload: MigrationCheckpointPayload

crc32c: u32

ts_ms: u64

Wall-clock milliseconds at proposal time (non-authoritative — used only for timeout-based abort decisions during recovery).

Implementations

pub fn migration_uuid(&self) -> Option<MigrationId>

Trait Implementations

impl Clone for PersistedMigrationCheckpoint

fn clone(&self) -> PersistedMigrationCheckpoint

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PersistedMigrationCheckpoint

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for PersistedMigrationCheckpoint

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<'__msgpack_de> FromMessagePack<'__msgpack_de> for PersistedMigrationCheckpoint

fn read<R: Read<'__msgpack_de>>(reader: &mut R) -> Result<Self, Error>

where Self: Sized,

Reads the MessagePack representation of this value from the provided reader.

impl PartialEq for PersistedMigrationCheckpoint

fn eq(&self, other: &PersistedMigrationCheckpoint) -> 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.

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl ToMessagePack for PersistedMigrationCheckpoint
