// Quick Start  Loading a native library

import fastcore.FastCore;

public class MyNativeApp {
    static {
        // Automatically extracts and loads fastnative.dll from resources
        FastCore.loadLibrary("fastnative");
    }
}

Key Features

• 📥 Smart Extraction: Automatically handles temporary file deployment for JNI DLLs.
• ⏱️ Zero Overhead: Minimalist design focused on JVM startup acceleration.
• 🔗 Ecosystem Base: Required dependency for all FastJava modules.

---

Performance

FastCore is designed to be the fastest way to bridge Java and Native code during the initialization phase.

Operation	FastCore	Standard System.load	Benefit
Library Extraction	< 5 ms	N/A (Manual)	Automated
JNI Mapping	Instant	Instant	Stable

Installation

Option 1: Maven (Recommended)

Add the JitPack repository and the dependencies to your pom.xml:

<repositories>
    <repository>
        <id>jitpack.io</id>
        <url>https://jitpack.io</url>
    </repository>
</repositories>
<dependencies>
   <dependency>
       <groupId>com.github.andrestubbe</groupId>
       <artifactId>fastcore</artifactId>
       <version>0.1.0</version>
   </dependency>
</dependencies>

Option 2: Gradle (via JitPack)

repositories {
    maven { url 'https://jitpack.io' }
}
dependencies {
    implementation 'com.github.andrestubbe:fastcore:0.1.0'
}

Option 3: Direct Download (No Build Tool)
