Struct ConnectionGuard

Source

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

Expand description

Exclusive access to the database connection

Note that this is only ever constructed when we already hold exclusive access, and the connection has already been tested to ensure that it is non-empty.

Methods from Deref<Target = KeystoreDatabaseConnection>§

Source

pub async fn conn(&self) -> MutexGuard<'_, Connection>

Trait Implementations§
