Enum deadpool_postgres::config::RecyclingMethod

pub enum RecyclingMethod {
    Fast,
    Verified,
}

This enum is used to control how the connection is recycled. Attention: The current default is Verified but will be changed to Fast in the next minor release of deadpool-postgres. Please make sure to explicitly state this if you want to keep using the Verified recycling method.

Variants

Fast

Only run Client::is_closed when recycling existing connections. Unless you have special needs this is a safe choice.

Verified

Run Client::is_closed and execute a test query. This is slower but guarantees that the database connection is ready to be used. Normally Client::is_closed should be enough to filter out bad connections but under some circumstances (i.e. hard-closed network connections) it is possible that Client::is_closed returns false but the connection is dead. You will receive an error on your first query then.
