Mustachers

Providing mustache rendering using Rust by wrapping the mustache crate.

At the moment only a simple render function taking a template file and parameters to interpolate. This does not look to replace or compete with the ruby offering, but provides an alternative seemingly offering a performance enhancement.

Install the gem and add to the application's Gemfile by executing:

$ bundle add mustachers

If bundler is not being used to manage dependencies, install the gem by executing:

$ gem install mustachers

Require the gem if needed. Some might be dynamically loaded.

require 'mustachers'

An example of using the gem.

Mustachers::Renderer.render("<h1>{{text}}</h1>", {text: "abc123"})

From the console.

bundle exec ruby -r mustachers -e 'puts Mustachers::Renderer.render("<h1>{{text}}</h1>", {text: "abc123"})'
<h1>abc123</h1>

The script for this can be found in the benchmarks directory.

bundle exec ruby benchmarks/simple.rb

TODO:

• Check Ruby performance such as any memory leaks and garbage collection.
• Improve the error handling to raise an appropriate error.
• Unit tests in rust to provide faster feedback while developing.
• More options for the template rendering such as reading the file.
• Benchmarking with different sized inputs.
