Method IsUsable

internal/pool/conn.go:278–285

IsUsable returns true if the connection is safe to use for new commands (lock-free). A connection is "usable" when it's in a stable state and can be returned to clients. It becomes unusable during: - Handoff operations (network connection replacement) - Re-authentication (credential updates) - Othe

()

// Note: CREATED state is considered usable because new connections need to pass OnGet() hook
// before initialization. The initialization happens after OnGet() in the client code.
func (cn *Conn) IsUsable() bool {
	state := cn.stateMachine.GetState()
	// CREATED, IDLE, and IN_USE states are considered usable
	// CREATED: new connection, not yet initialized (will be initialized by client)
	// IDLE: initialized and ready to be acquired
	// IN_USE: usable but currently acquired by someone
	return state == StateCreated || state == StateIdle || state == StateInUse
}

// SetUsable sets the usable flag for the connection (lock-free).
