# `wasmer-engine` [![Build Status](https://github.com/wasmerio/wasmer/workflows/build/badge.svg?style=flat-square)](https://github.com/wasmerio/wasmer/actions?query=workflow%3Abuild) [![Join Wasmer Slack](https://img.shields.io/static/v1?label=Slack&message=join%20chat&color=brighgreen&style=flat-square)](https://slack.wasmer.io) [![MIT License](https://img.shields.io/github/license/wasmerio/wasmer.svg?style=flat-square)](https://github.com/wasmerio/wasmer/blob/master/LICENSE)

This crate is the general abstraction for creating Engines in Wasmer.

Wasmer Engines are mainly responsible for two things:
* Transform the compilation code (from any Wasmer Compiler) to
  **create** an `Artifact`,
* **Load** an`Artifact` so it can be used by the user (normally,
  pushing the code into executable memory and so on).

It currently has three implementations:

1. Universal with [`wasmer-engine-universal`],
2. Native with [`wasmer-engine-dylib`],
3. Object with [`wasmer-engine-staticlib`].

## Example Implementation

Please check [`wasmer-engine-dummy`] for an example implementation for
an `Engine`.

### Acknowledgments

This project borrowed some of the code of the trap implementation from
the [`wasmtime-api`], the code since then has evolved significantly.
