# Perl XS for Rust

High-level Rust bindings to Perl XS API.

## Example

```rust

xs! {

  package Array::Sum;

  sub sum_array(ctx, array: AV) {

    array.iter().map(|it| it.unwrap_or(0.0)).sum::()

  }

}

```

For a more complete example see the XSTest package in the `t/` directory.

## Goals

- safety

- correctness

- speed

Perl XS API is deliberately low-level and requires user to maintain a

good deal of internal invariants, thus allowing for very fast

code. This package takes a different approach of encapsulating

implementation details to provide a simpler and safer API at the cost

of speed.

For now, this library focuses on Perl's public documented API, which

is a small subset of what is available to authors of modules written

in C.

## Work in progress

This project is very much in progress. It is not yet clear if project

goals are attainable at all or if the API will make any sense in

practice.

## How to use

`Module::Install::Rust` integrates traditional Perl build system with

Cargo, allowing Rust code to be compiled and installed using familiar

`perl Makefile.PL && make` process. For example, see test package

under `t` directory.

## Prerequisites

- Perl 5.20+ (for 64-bit array methods)

- Rust 1.31+

## Testing

To install packages required for testing and benchmarking:

```shell

cpanm --installdeps .

```

To run tests:

```shell

(cd t && perl Makefile.PL && make test)

```
