Standard Library

Wuffs' standard library consists of multiple packages, each implementing a particular file format or algorithm. Those packages can be grouped into several categories:

The general pattern is that a package foo (e.g. jpeg, png) contains a struct bar (e.g. hasher, decoder, etc) that implements a package-independent interface. For example, every compression decoder struct would have a transform_io method. In C, this would be invoked as

// Allocate and initialize the struct.
wuffs_foo__decoder* dec = etc;

// Do the work. Error checking is not shown, for brevity.
const char* status = wuffs_foo__decoder__transform_io(dec, etc);

When that C library is used as C++, that last line can be shortened:

const char* status = dec->transform_io(etc);
