Module rusqlite::vtab[−][src]

Expand description

feature = "vtab" Create virtual tables.

Follow these steps to create your own virtual table:

Write implementation of VTab and VTabCursor traits.
Create an instance of the Module structure specialized for VTab impl. from step 1.
Register your Module structure using Connection::create_module.
Run a CREATE VIRTUAL TABLE command that specifies the new module in the USING clause.
