About

GenericItem is a data structure that can hold int, char... and even custom data structures! This project was mainly made for my learning but it's actually very useful.

Important

Intrisics/SIMD are used and only machines with AVX2 are supported at the moment. (Although most x86-64 machines should)

Data Structures/Types

These are the built-int types that GenericItem can hold:

• int
• bool
• char
• char *
• float
• double
• void *

Custom Data Structures (found in src & include):

• Vector *
• HashMap *
• Set *
• LinkedList *
• Queue *
• DLinkedList *
• BST *

Example

Here's a little example of how you can use it

#include <stdlib.h>
#include <stddef.h>
#include <stdio.h>

#include "complex_generic_item.h"
#include "arena.h"
#include "vector.h"
#include "hashmap.h"

int main() {
    Arena *arena = arena_init();
    if (arena == NULL) {
        return -1;
    }

    Vector *vector = vector_init(arena);
    if (vector == NULL) {
        goto cleanup;
    }

    vector_append_item(arena, vector, convert_item(10));
    vector_append_item(arena, vector, convert_item("Sacul"));

    HashMap *map = map_init(arena);
    if (map == NULL) {
        goto cleanup;
    }
    map_insert_item(arena, map, convert_item("spider"), convert_item("man"));
    vector_append_item(arena, vector, convert_item(map));

    print_item(convert_item(vector)); // [10, "Sacul", {"spider": "man", }, ]
cleanup:
    arena_destroy(arena);
}

Want a more complex use case? Here's a little JSON-Parser that I made using GenericItem!

First, run this in the root directory which compiles the example:

make json_parser

Then execute it:

.\json_parser
