Implementations

impl<Tls> ConnectionBuilder<Tls>

where Tls: MakeTlsConnect<Socket> + Clone + Send + Sync + 'static, Tls::Stream: Sync + Send, Tls::TlsConnect: Sync + Send, <Tls::TlsConnect as TlsConnect<Socket>>::Future: Send,

pub fn tls<NewTls>(self, tls: NewTls) -> ConnectionBuilder<NewTls>

where NewTls: MakeTlsConnect<Socket> + Clone + Send + Sync + 'static, NewTls::Stream: Sync + Send, NewTls::TlsConnect: Sync + Send, <NewTls::TlsConnect as TlsConnect<Socket>>::Future: Send,

Set the Tls method.

Use either postgres-openssl or postgres-nativ-tls and their respective documentation. This function accepts the same types as tokio-postgres.

pub fn max_pool_size(self, n: usize) -> Self

Set the maximum size of the connection pool, i.e. the maximum amount of concurrent connections to the database server.

The default is num_cpus * 4, ignoring hyperthreading, etc.

pub fn connect(self) -> Result<(), Error>

Finish the setup and build the pool.

Fails if

• the url couldn’t be parsed, or
• some other configuration error has been made.
