Struct FindPkByIndex 

pub struct FindPkByIndex {
    pub table: TableId,
    pub index: IndexId,
    pub filter: Expr,
}

Looks up primary keys through a secondary index.

The driver queries the specified secondary index using filter and returns the matching primary key values. The query engine then uses those keys in a subsequent GetByKey operation to fetch full records.

Examples

use toasty_core::driver::operation::{FindPkByIndex, Operation};

let op = FindPkByIndex {
    table: table_id,
    index: index_id,
    filter: filter_expr,
};
let operation: Operation = op.into();

Fields

table: TableId

The table that owns the index.

index: IndexId

The secondary index to query.

filter: Expr

Filter expression applied against the index columns.
