Enum RecoveryState 

pub enum RecoveryState {
    CleanShutdown,
    DirtyShutdown,
    PartialCheckpoint,
    CorruptWAL,
    CorruptGraphFile,
    Unrecoverable,
}

Explicit recovery state determined from existing signals

Variants

CleanShutdown

No recovery needed - clean shutdown detected

DirtyShutdown

Dirty WAL with uncommitted transactions - requires recovery

PartialCheckpoint

Partial checkpoint in progress - resume checkpoint operation

CorruptWAL

WAL file is corrupted - cannot recover

CorruptGraphFile

Graph file is corrupted - cannot recover

Unrecoverable

Both WAL and graph file corrupted - unrecoverable

Implementations

impl RecoveryState

pub fn determine_from_files( wal_exists: bool, graph_file_exists: bool, checkpoint_exists: bool, wal_header: Option<&V2WALHeader>, _graph_file_size: Option<u64>, ) -> NativeResult<Self>

Determine recovery state from existing files and headers

This method uses ONLY existing signals from the files:

• WAL header magic, version, and LSN relationships
• Graph file existence and header validation
• Checkpoint file existence and LSN ranges

No new heuristics or assumptions are introduced.

pub fn requires_recovery(&self) -> bool

Check if recovery is required

pub fn is_recoverable(&self) -> bool

Check if recovery is possible

pub fn severity(&self) -> RecoverySeverity

Get recovery severity level for diagnostics

Trait Implementations

impl Clone for RecoveryState

fn clone(&self) -> RecoveryState

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RecoveryState

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for RecoveryState

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for RecoveryState

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

Formats the value using the given formatter.

impl Ord for RecoveryState

fn cmp(&self, other: &RecoveryState) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for RecoveryState

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

impl PartialOrd for RecoveryState

fn partial_cmp(&self, other: &RecoveryState) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for RecoveryState

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
