Enum IndexLookup 

pub enum IndexLookup<'value> {
    All,
    Equal(&'value PropertyValue),
    Range {
        min: &'value PropertyValue,
        max: &'value PropertyValue,
    },
    CompositeEqual(&'value [PropertyValue]),
}

Lookup input for a cataloged index.

This type makes index lookup shape explicit: membership indexes accept IndexLookup::All, single-property indexes accept scalar equality or range inputs, and composite equality indexes accept an ordered value tuple.

Performance

Copying this value is O(1).

Variants

All

Lookup every subject represented by a membership-style index.

Equal(&'value PropertyValue)

Lookup one scalar equality value.

Range

Lookup one inclusive scalar range.

Fields

min: &'value PropertyValue

Inclusive lower bound.

max: &'value PropertyValue

Inclusive upper bound.

CompositeEqual(&'value [PropertyValue])

Lookup one ordered composite equality tuple.
