Struct ReadTxn 

pub struct ReadTxn<'a> { /* private fields */ }

Concurrent read view pinned at a revision ceiling.

Implementations

impl<'a> ReadTxn<'a>

pub fn new(db: &'a InfiniteDb) -> Self

Pin reads at the current database revision on main.

pub fn on_branch(self, branch: BranchId) -> Self

Read through a branch overlay instead of main.

pub fn as_of(self, rev: RevisionId) -> Self

Override the revision ceiling for this read view.

pub fn query(&self, space: SpaceId) -> Result<Vec<Record>>

Query all live records in space within this read view.

pub fn query_bbox( &self, space: SpaceId, min: DimensionVector, max: DimensionVector, ) -> Result<Vec<Record>>

Bounding-box query within this read view.

pub fn execute(&self, q: &Query) -> Result<Vec<Record>>

Execute a Query descriptor against this read view.

When q.range is set, an exact per-record coordinate filter is applied so results match InfiniteDb::query_bbox.
