# Rust plugin

The binaries produced by the Rust compiler have some peculiarities which make them difficult to analyze, such as:

```
  - non-standard calling conventions
  - non-terminated string literals
  - unusual name mangling scheme
```

By default, Rust plugin is enabled if one of the following condition is true

```
  - one address is named 'rust_begin_unwind'
  - the string 'rustc-' can be found somewhere in the program
    If the segment '.rodata' exists, the search is limited to this segment
```

## String literal analysis

Rust plugin walks to all addresses in segment with name ending in "\_\_const", ".rodata" or ".rdata" and creates string literals on xref

```
  - on dref, the string literal is set up to the next dref
  - on cref, Rust tries to retrieve length from nearby instructions
    Arm, Risc-V and pc proc module benefit from this
```

To force the string literal detection:

```
  idaapi.load_and_run_plugin("rust", 1)
```

## Demangling name

Rust plugin also offers the possibility to configure a demangler library for rust. By default the plugin will use the librustdemangle library that is shipped with IDA. You can disable this feature in 'Edit>Plugin>Rust language helper' or specify another library to use.

See cfg/rust.cfg for the possible options

## List of '-Orust' options

```
  - on  : enable rust plugin for this session of IDA
  - off : disable rust plugin for this session of IDA
```

## Example

```
  -Orust:off
```

This disable the plugin for this session of IDA.
