rust.mk

This plugin for erlang.mk enables the automatic building of Rust crates in an Erlang application. The plugin will build all crates in the crates directory and copy all binary outputs to priv/crates/<cratename>/<binary>. See the test application in this repository for an example of a port program and NIF module implemented in Rust.

Using the plugin

Use the plugin by adding BUILD_DEPS and DEP_PLUGINS as in this Makefile:

PROJECT = myapp
BUILD_DEPS = rust_mk
DEP_PLUGINS = rust_mk

include erlang.mk

This will automatically download and use rust.mk.

Application structure with Rust crates

To add crates to an Erlang application, place them in a crates/ folder. All crates found within will be built and resulting artifacts will be placed in the priv/crates/ folder.

The library application find_crate may be used to reliably find artifacts in priv/crates in a cross-platform manner.
