Typedef Documentation

◆ af_index_t

typedef struct af_index_t af_index_t

Struct used to index an af_array.

This struct represents objects which can be used to index into an af_array Object. It contains a union object which can be an af_seq or an af_array. Indexing with an int can be represented using a af_seq object with the same af_seq::begin and af_seq::end with an af_seq::step of 1
