Struct KeyValueReadRevision 

pub struct KeyValueReadRevision(/* private fields */);

Opaque cache identity. Numeric index revisions alone do not distinguish undo branches or independent private transactions.

Implementations

impl KeyValueReadRevision

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

Compare private changes for the same selected prefixes, independently of intervening committed writes. Unversioned or individual-record identities cannot establish this property.

pub fn has_private_changes(&self) -> bool

Whether the selected record prefixes include changes private to this transaction. Unversioned view identities conservatively report private state because they cannot prove committed provenance.

pub fn fresh() -> Self

Allocate a distinct identity for a provider-owned view. Retain and clone it while that view is unchanged; allocate a fresh identity after writes or undo instead of reusing a numeric counter.
