The nano "template" free data structure library.

Data structures don't know the size of the stored data, so in most cases you need to explicitly pass sizeof(type). For example, consider the vector of an allocated array called vec.

// Creation of a new vec
vec v = vec_new();

// .. with initial capacity
vec v = vec_with_cap(6, sizeof(u32));

// Push data in vec
u32 n = 12;
vec_push(&v, &i, sizeof(u32));

// Pop data from vec
u32 *val = vec_pop(&v, sizeof(u32));

// Drop the vec
vec_drop(&v);

There are also more additional structures such as slice, lmap, box, etc.
