ML -Modeling Language-

Crate travis-badge appveyor-badge dependencyci-badge

A library (and cli tool) to generating UML language from Rust's project into graphiz/dot file.


Obtain mml

$ git clone https://github.com/silence-coding/ml.git
$ cd ml

Install Dependencies

The dot binary from graphviz package must exist in your path.

$ apt install graphviz

(or do the equivalent for your OS)

Nightly rustc is required. Run this from within ml crate.

$ rustup install rustc llvm-tools-preview

Build and run mml

$ cargo run --example ml

important: ml looks for files beneath ./src, so you should always cd to crate root before running it.

View generated diagram

$ firefox target/doc/ml.svg

inkscape also works well as an svg viewer.


$ ./target/debug/examples/ml --help Usage: ml [OPTIONS]

Parses rust source code and generates UML diagram

--include_fields [bool] include fields/variants in diagram
--include_implems [bool] include trait implementation methods in diagram
--include_methods [bool] include methods in diagram
--struct_header_bgcolor [str] header background color for structs
--struct_fields_bgcolor [str] fields background color for structs
--struct_method_bgcolor [str] methods background color for structs
--struct_implem_bgcolor [str] implems background color for structs
--enum_header_bgcolor [str] header background color for enums
--enum_fields_bgcolor [str] fields background color for enums
--enum_method_bgcolor [str] methods background color for enums
--enum_implem_bgcolor [str] implems background color for enums
--trait_header_bgcolor [str] header background color for traits
--trait_method_bgcolor [str] methods background color for traits
--font [str] Font name

Output is always under target/doc/mml/

You can add ml binary to your path and then you should be able to run it for any rust crate.

--------------------------- Old, possibly obsolete -----------------


This repo is provided as a Cargo package and a build script.

  1. adjust your Cargo.toml to include.
build = "build.rs"

version = "0.0.1"
  1. And your build.rs to generate your uml graph/viz and Structured Vector Graphics at target/dot/$CARGO_PKG_NAME.{dot,svg}.
extern crate mml;

fn main() {
    let dest: String = concat!("target/doc/", env!("CARGO_PKG_NAME")).to_string();
    let mut config = rust2uml::Config::default();
    let _ = rust2uml::src2both("src", dest.replace("-", "_").as_str());
  1. (Facultative) From your entry point library file, you can add the generated vectorized graph.
//! ![uml](ml.svg)
  1. (Facultative) With the travis-cargo's instructions, you can prepare your graphviz's dependency like with this example.
      - graphviz
  - if [[ "$TRAVIS_OS_NAME" == "osx" ]]; then brew update           ; fi
  - if [[ "$TRAVIS_OS_NAME" == "osx" ]]; then brew install graphviz ; fi
  - |
      travis-cargo build &&


Consider this list of fonctionalities like unstandard-uml.

  • implem -- add a column to show the functions from a implementation.
  • fn-emilgardis -- the function fields are preceded by fn keyword (Asked by Emilgardis).


This is a reading list of material relevant to Ml. It includes prior research that has - at one time or another - influenced the design of Ml, as well as publications about Ml.
