jvmti-rust
An extensible, safe native JVM agent implemented in pure Rust.
A word of warning
This project is far from being complete or usable to say the least and contains a healthy dose of proof-of-concept code that is guaranteed to either work or not.
Abstract
Rust JVMTI is intended to become a slim JVM application performance management (APM) tool leveraging both safe access to native JVM functionality via Rust and byte code instrumentation using Java code.
Already implemented (probably poorly)
- Ability to connect to a JVM as a native agent library
- Read and parse loaded class files
- Generate byte code from loaded or created class files
- Gathering and displaying statistics about method class, class loading and synchronization times
- Read basic command line configuration
- Basic JVM emulator for implementing unit tests without the need for an actual JVM
Usage
Please see the example.
