Struct IndexSpec 

pub struct IndexSpec {
    pub column: String,
    pub entity_columns: Vec<String>,
    pub kind: IndexKind,
}

Canonical ordered-index configuration for a time-series table.

Fields

column: String

Name of the single ordered index column.

entity_columns: Vec<String>

Optional ordered entity columns used for entity-scoped coverage.

kind: IndexKind

Ordered value domain and coverage bucket configuration.

Implementations

impl IndexSpec

pub fn validate(&self) -> Result<(), IndexSpecError>

Validate structural invariants that do not require a logical schema.

Errors

Returns IndexSpecError for an empty index column, an empty entity column, a duplicate entity column, or an entity column that is also the ordered index.
