+**Status:** Currently, the plugin is under extensive development. It is far from maturity. But a working prototype can be expected within a few weeks.

+This project was a part of one of my institute courses. For a detailed overview, please have a look at the [report](./media/report.pdf) created for the course submission. The following README is fairly sparse.

+## Features
+
+### Rust binary detection
+
+The plugin can detect Rust binaries. To use the feature, click on `GhidRust -> Check if Rust binary`. It will show a popup indicating whether it's a Rust binary or not.

+
+### Function ID
+
+The plugin also consists of `RustStdAnalyzer` which analyzes Rust binaries and applies function signatures to the library functions (Rust's `std`) found in the binary. This is done using `.fidb` function ID database. A default database for x86-64 and Rust version 1.58.1 has been provided at [`libstd.fidb`](./data/libstd-4c74cbab78ec4891.fidb). This is useful when analyzing stripped Rust binaries.

+
+The analyzer is enabled by default for Rust binaries, and it's name in analyzer window is _"Detect Rust libstd functions"_.

+
+### Decompilation
+
+This is a work-in-progress feature as of now. It requires parsing the decompiled C code and then emitting the corresponding Rust code. Once that is done, Rust macro support will also be added in the future.
+
+The decompiler panel can be accessed by clicking `GhidRust -> Open decompiler`. It looks as follows.

 ## Building
 
 There is a build script provided (`build.sh`) which can build and install the extension.

+## Adding it to Ghidra
+
+To add it to Ghidra, just click on `File -> Install Extensions...` and choose GhidRust there. Once installed, you will have a `GhidRust` entry in the Ghidra toolbar which can be used to invoke the plugin.
