pub struct PoolManager { /* private fields */ }Expand description
Shared pool cache with verified publication. A pool becomes visible
only after Pool::get_conn() + a SELECT 1 health query succeed on it.
Implementations§

pub fn new() -> Self

&self,
conn: &MySqlConnection,
password: &Zeroizing<String>,

pub async fn verified_pool( &self, conn: &MySqlConnection, password: &Zeroizing<String>, database: Option<&str>, revision: u64, host_override: Option<&str>, port_override: Option<u16>, tunnel_generation: Option<u64>, ) -> Result<Pool, PoolManagerError>
Return a verified pool for this configuration+credential, initializing (handshake + health query) at most one pool per key even under concurrent first access. Superseded pools are closed and evicted. Auth/DNS/TLS/handshake failures never populate the cache.
