Struct Query 

pub struct Query<'q, 's, S: RangeSource> { /* private fields */ }

Metadata-only generation guard shared by material lookup and archive input coverage. It cannot replace the original document’s source or execution.

Trait Implementations

impl<'q, S: RangeSource> Query for Query<'q, '_, S>

type Id = Node

Original node identity.

type Document = <S as RangeSource>::Document

Stable document identity.

type Generation = <S as RangeSource>::Generation

Exact document generation.

type Work = Execution<'q>

Current execution funding this query.

fn snapshot(&self) -> Snapshot<Self::Document, Self::Generation>

The expected source snapshot of every fact checked in this query.

fn execution(&self) -> &Self::Work

The current execution; storage and work for results are admitted here.

fn admit(&self, node: Node, units: u64) -> Result<(), ScopeError<Node>>

Requires the live source at the expected snapshot, admits units of work, and requires the snapshot again.

fn equal(&self, left: Self::Id, right: Self::Id) -> Result<bool, MemoryError>

Compares two identities after admitting their complete HashWork.
