type Limiter struct {
	// contains filtered or unexported fields
}

Limiter is shared by every connection of one user. Upload is what the client sends, download what it receives; each direction gets the full rate.

func New(bytesPerSecond uint64) *Limiter

New returns a limiter for bytesPerSecond in each direction, which must be positive.

func (l *Limiter) Conn(ctx context.Context, conn net.Conn) net.Conn

Conn throttles conn, the client side of a proxied connection.

func (l *Limiter) PacketConn(ctx context.Context, conn N.PacketConn) N.PacketConn

PacketConn throttles conn, the client side of a proxied packet connection.

func (l *Limiter) SetLimit(bytesPerSecond uint64)

SetLimit changes the rate for existing connections too.
