Enum MetadataRowFamily 

pub enum MetadataRowFamily {
    Inodes,
    DirentryBinds,
    DirentryChildBinds,
    DirentryUnbinds,
    Revisions,
    Tombstones,
    ActiveDeletions,
    CommitReceipts,
    ContentPublications,
    Attributes,
    Access,
}

Selects a metadata row family and its durable lookup ordering.

See metadata rows and row keys.

Variants

Inodes

Stores inode identity, kind, and creation position.

DirentryBinds

Orders directory bindings for parent-and-name visibility lookups.

DirentryChildBinds

Re-indexes directory bindings by child for parent discovery.

DirentryUnbinds

Stores immutable events that retire exact historical bindings.

Revisions

Stores file revisions newest-first within each inode.

Tombstones

Stores set and revoke events used to determine active subtree tombstones.

ActiveDeletions

Names the deletions that are recoverable right now, derived from the tombstone family and ordered by deletion time.

CommitReceipts

Preserves commit idempotency evidence independently of retained WAL history.

ContentPublications

Preserves evidence that content was published.

Attributes

Stores inode attribute revisions newest-first.

Attributes are read only in this order, so the family has no secondary index and requires no cross-family parity check.

Access

Stores inode access revisions newest-first.

Access rows are read only in this order, so the family has no secondary index and requires no cross-family parity check.

Implementations

impl MetadataRowFamily

pub const fn as_str(self) -> &'static str

Returns the snake-case name used in durable keys and serialized values.

pub const fn row_key_prefix(self) -> &'static str

Fixed prefix before the first variable component in this family’s row keys. Compaction uses the remaining components to group rows for retention.

Trait Implementations

impl Clone for MetadataRowFamily

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for MetadataRowFamily

impl Debug for MetadataRowFamily

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for MetadataRowFamily

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for MetadataRowFamily

impl Ord for MetadataRowFamily

fn cmp(&self, other: &Self) -> 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.

fn clamp_to<R>(self, range: R) -> Self

where Self: Sized, R: ClampBounds<Self>,

🔬This is a nightly-only experimental API. (clamp_to)

Restrict a value to a certain range.

impl PartialEq for MetadataRowFamily

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for MetadataRowFamily

fn partial_cmp(&self, other: &Self) -> 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 MetadataRowFamily

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
