Provided Methods

fn create( db: &mut VTabConnection, aux: Option<&Self::Aux>, args: &[&[u8]], ) -> Result<(String, Self)>

Create a new instance of a virtual table in response to a CREATE VIRTUAL TABLE statement. The db parameter is a pointer to the SQLite database connection that is executing the CREATE VIRTUAL TABLE statement.

Call connect by default. (See SQLite doc)

fn destroy(&self) -> Result<()>

Destroy the underlying table implementation. This method undoes the work of create.

Do nothing by default. (See SQLite doc)

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
