Struct StoreOptions 

pub struct StoreOptions {
    pub graph_index: bool,
    pub text_index: bool,
    pub versioning: Versioning,
    pub stamp_index: bool,
    pub as_of_index: bool,
}

Options chosen when a store is created.

Fields

graph_index: bool

Create the optional quads_gspo index (fast GRAPH <g> { ?s ?p ?o }, CLEAR GRAPH).

text_index: bool

Create the full-text index over string literals (FTS5, see crate::text).

versioning: Versioning

How much history the store keeps (see crate::version); Off by default. Applied when the store is created; an existing store changes level only through an explicit level change.

stamp_index: bool

With stamped or log: index quads.t (fast “added since” queries, one more row written per quad).

as_of_index: bool

With log: index the change log by predicate and object too (fast as-of queries on any pattern, two more rows written per change).

Implementations
