libdr-in-rust

try to make libdr like in rust

libdr is the first big project in 42.fr school, originaly this is in C but for funny i try to make this is rust

let's start this

:)

🗣️ About

In 42 campus you can use only sommes lib's for the 'baned functions' you need to code that yourself, here i just make that with rust for train myself with rust.

For detailed information from original project, refer to the subject of this project.

🚀 TLDR: this project consists of coding basic C functions (see below).

Unlike 42 my functions are not prefixed ft_ , I love prefix with dn_ for local and dr_ for global functions

🛠️ Usage

Requirements

The library is written in Rust language and thus needs the cargo compiler and some standard rust libraries to run.

Instructions

1. Compiling the library

To compile the library, run:

$ cd path/to/libdr && make

2. Using it in your code

To use the library functions in your code, simply include its header:

use dr_libdr::{dn_myfunction}

📋 Testing

1. First, configure the path to the libdr folder in the Makefile (inside /testing/):

#############################
## Path to Libdr directory ##
#############################
DIR		= ../

2. Then run:

make t
