Educational immutable, persistent vector implementation in C, inspired by the Clojure vector implementation.
Have a look at main.c to get started. Run make && ./ipvec to build run the demo program.
Note that this is educational and there's really no memory management. I leave this detail as an exercise for the reader (hint: count refernces or implement GC and free() Node structs when dead.)
typedef struct IPVec IPVec;
// An opaque structure representing a vector.
extern const IPVec* IPVecEmpty;
// The empty vector. This is usually what you will start with when building
// a new vector.
IPVec* IPVecPut(const IPVec* v, size_t index, void* value);
// Derive a vector from v which has value at index
IPVec* IPVecAppend(const IPVec* v, void* value);
// Derive a vector from v which has value at the end of v
void* IPVecAt(const IPVec* v, size_t index);
// Return the value at index, or NULL if not set
size_t IPVecLen(const IPVec* v);
// Return the virtual length of v. Note that IPVec is sparese, and thus a
// vector with only two items can have a length greater than 2.Copyright (c) 2013 Rasmus Andersson http://rsms.me/
