Enum PopulationSelector 

#[non_exhaustive]
pub enum PopulationSelector {
    All,
    Rows(Arc<[usize]>),
    Environment {
        env_index: usize,
    },
    TimeRange {
        start: usize,
        end: usize,
    },
}

Population / period selector for change attribution.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

All

All rows of the bound table.

Rows(Arc<[usize]>)

Explicit row indices into a tabular view.

Environment

Multi-environment index (resolved against [EnvironmentId] maps at call sites).

Fields

env_index: usize

Dense environment index into a multi-env container.

TimeRange

Inclusive-exclusive time/row range [start, end).

Fields

start: usize

Start index (inclusive).

end: usize

End index (exclusive).

Implementations
