Enum RecordKind 

#[repr(u8)]
pub enum RecordKind {
    CreateEntity = 0,
    CreateRelation = 1,
    AddObservations = 2,
    DeleteEntity = 3,
    DeleteObservations = 4,
    DeleteRelation = 5,
    TxnBegin = 6,
    TxnCommit = 7,
}

Variants

CreateEntity = 0

CreateRelation = 1

AddObservations = 2

DeleteEntity = 3

DeleteObservations = 4

DeleteRelation = 5

TxnBegin = 6

Opens a transaction: records that follow are buffered on replay and only applied once a matching RecordKind::TxnCommit is seen. An unclosed transaction (no commit before EOF) is discarded — this is how multi-record operations like merge_entities stay crash-atomic.

TxnCommit = 7

Closes a transaction opened by RecordKind::TxnBegin.

Implementations

impl RecordKind

pub const fn from_u8(v: u8) -> Option<RecordKind>

Trait Implementations

impl Clone for RecordKind

fn clone(&self) -> RecordKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for RecordKind

impl Debug for RecordKind

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

Formats the value using the given formatter.

impl Eq for RecordKind

impl PartialEq for RecordKind

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