Struct IndexIntent 

Source 
pub struct IndexIntent {
    pub name: &'static str,
    pub column: &'static str,
    pub trigger: IndexTrigger,
    pub params: IndexParamsKind,
}
Expand description

Declarative description of one index pond keeps on a table. Created when its trigger fires; folded forward by pond index optimize.

Fields§

§name: &'static str

Stable on-disk name. Must match across runs so existence checks resolve.

§column: &'static str

Column the index covers.

§trigger: IndexTrigger

Condition evaluated against the live dataset before each cycle.

§params: IndexParamsKind

How the params are built at create time. Some intents have static params (FTS, scalars); IVF_PQ needs the row count to size partitions.
