📚 Read this template tutorial! 📚

This template is designed for compiling Rust libraries into WebAssembly and publishing the resulting package to NPM.

Be sure to check out other wasm-pack tutorials online for other templates and usages of wasm-pack.

🚴 Usage

🐑 Use cargo generate to Clone this Template

Learn more about cargo generate here.

cargo generate --git https://github.com/rustwasm/wasm-pack-template.git --name my-project
cd my-project

🛠️ Build with wasm-pack build

wasm-pack build

🔬 Test in Headless Browsers with wasm-pack test

wasm-pack test --headless --firefox

🎁 Publish to NPM with wasm-pack publish

🔋 Batteries Included

• wasm-bindgen for communicating between WebAssembly and JavaScript.
• console_error_panic_hook for logging panic messages to the developer console.
• wee_alloc, an allocator optimized for small code size. # Rust playground

Things I have recently done while learning the Rust programming language.

Synopsis

Change in one of the toplevel subdirectories and try cargo build or cargo run. Maybe not everything is working oob. Feel free to fix whatever you want.

Description

Various small examples I have tried while learning rust. The biggest and currently most active project is fractional which started as an implamentation of a rational number data type and then switched to a 3D math playground visualizing using XCB (in future it might also use a HTML5 Canvas for drawing as WebAssembly application. Using fractions with 3D math has several drawbacks:

1. A huge part of 3D math is non rational, like sin, cos, tan and sqrt.
2. The numerator and denominator tend to become very huge while nearing to non rational numbers and reduction is difficult and time consuming.
3. Because of 2 it is way slower than the floating point calculation (at least with a decent coprocessor).

Anyway, implementing the vector math stuff for both fractions and floating point was a nice playground for generics and traits. In future I might add another data type which implements the math as done by David Braben for the elite computer game.

Requirements

Always

• A recent version of the Rust programming language as well as tooling. Currently I use Rust 1.39.0.

For fractional

• A running X Server with XCB and X11-SHM extentions
