Function takeInflows

internal/http2/flow.go:68–75

takeInflows attempts to take n bytes from two inflows, typically connection-level and stream-level flows. It reports whether both windows have available capacity.

(f1, f2 *inflow, n uint32)

// typically connection-level and stream-level flows.
// It reports whether both windows have available capacity.

	if n > uint32(f1.avail) || n > uint32(f2.avail) {
		return false
	}
	f1.avail -= int32(n)
	f2.avail -= int32(n)
	return true
}
