sourcepub fn new<S: Into<String>>(database_url: S) -> Self
pub fn new<S: Into<String>>(database_url: S) -> Self
Returns a new connection manager, which establishes connections to the given database URL.
sourcepub fn update_database_url<S: Into<String>>(&mut self, database_url: S)
pub fn update_database_url<S: Into<String>>(&mut self, database_url: S)
Modifies the URL which was supplied at initialization.
This does not update any state for existing connections, but this new URL is used for new connections that are created.
