VirtualTableModule

public protocol VirtualTableModule

The protocol for SQLite virtual table modules. It lets you define a DSL for the Database.create(virtualTable:using:) method:

let module = ...
try db.create(virtualTable: "items", using: module) { t in
    ...
}

GRDB ships with three concrete classes that implement this protocol: FTS3, FTS4 and FTS5.
