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:
- A huge part of 3D math is non rational, like sin, cos, tan and sqrt.
- The numerator and denominator tend to become very huge while nearing to non rational numbers and reduction is difficult and time consuming.
- 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
Dependencies
