Functions

func Creds

func Creds(ctx context.Context, ds *DialSettings) (*google.Credentials, error)

Creds returns credential information obtained from DialSettings, or if none, then it returns default credential information.

func QuotaProjectFromCreds

func QuotaProjectFromCreds(cred *google.Credentials) string

QuotaProjectFromCreds returns the quota project from the JSON blob in the provided credentials.

NOTE(cbro): consider promoting this to a field on google.Credentials.

Types

type ConnPool

type ConnPool interface {
	// Conn returns a ClientConn from the pool.
	//
	// Conns aren't returned to the pool.
	Conn() *grpc.ClientConn

	// Num returns the number of connections in the pool.
	//
	// It will always return the same value.
	Num() int

	// Close closes every ClientConn in the pool.
	//
	// The error returned by Close may be a single error or multiple errors.
	Close() error

	// ConnPool implements grpc.ClientConnInterface to enable it to be used directly with generated proto stubs.
	grpc.ClientConnInterface
}

ConnPool is a pool of grpc.ClientConns.
