Crate ristretto_jimage 

Ristretto JImage

Getting Started

JImage is a file format introduced in Java 9 to store Java runtime resources efficiently. This crate provides a reader for JImage files, allowing you to access and manipulate the resources contained within them.

Examples

use ristretto_jimage::Image;
use std::path::PathBuf;

fn main() -> ristretto_jimage::Result<()> {
    // Typically found at $JAVA_HOME/lib/modules
    let path = PathBuf::from("/path/to/java/lib/modules");
    let image = Image::from_file(&path)?;
    let resource_name = "/java.base/java/lang/Object.class";
    let resource = image.get_resource(resource_name)?;
    assert_eq!(resource_name, resource.full_name());
    Ok(())
}
