Struct IndexSpec 

pub struct IndexSpec {
    pub name: String,
    pub field: String,
    pub unique: bool,
    pub case_insensitive: bool,
    pub state: IndexState,
    pub predicate: Option<String>,
}

Secondary index metadata surfaced to the SQL planner.

Fields

name: String

field: String

Canonical field path ($.email, $.user.name, or plain column name for strict documents — the catalog layer stores them uniformly).

unique: bool

case_insensitive: bool

state: IndexState

Build state. Only Ready indexes drive query rewrites.

predicate: Option<String>

Partial-index predicate as raw SQL text (WHERE <expr> body without the keyword), or None for full indexes. The planner uses this to reject rewrites whose WHERE clause doesn’t entail the predicate — matching against such a partial index would omit rows the index didn’t cover.
