An image.Image is an interface type that can hold arbitrary image types (RGBA, greyscale, fixed-palette, and so on). The raster library only handles a specific subset of image types. Our moustache routine draws on an *image.RGBA. A user might upload any kind of image, so we may need to convert it before we can draw on it.

Parse string to int golang Golang has an inbuilt package called strconv that provide functions that convert string to int. The Atoi() Sscanf(), and ParseInt() are three functions that convert Golang string to int. Go is the statically typed language, data types are bound to variables rather than its values.

methods, even ones that didn’t explicitly attempt to satisfy (or even know about) the interface. Part of the reason interfaces are widely used in Go is that they are lightweight, with no annotations or explicit type hierarchy to main-tain. Web servers We started a few web servers indirectly in the last session. Let’s look at how that worked.
