Struct Connection

pub struct Connection<'a> { /* private fields */ }

A connection to a database backend.

This is a wrapper around the actual connection to the database.

Implementations

impl Connection<'_>

pub fn count(&self) -> usize

Count the number of queries that have been executed since the connection was created.

This is useful for testing to ensure that the expected number of queries have been executed against the database.
