Concurrency in Rust - Mandelbrot set

An introduction to Rust Concurrency using the Mandelbrot set.

Taken from the O'Reilly "Programming Rust" book.

Read the Slides, then compare main.rs, main-bands.rs and main-task-queue.rs.

The code for the concurreny algoithms is from https://github.com/ProgrammingRust/mandelbrot.

The main contribution beyond the book is to compare the output of the simpler z = z * z vs z = z * z + c.

The arguments are easier too making exploration of the Mandelbrot set easier, the boundaries are now just specified as with standard CSS edges TOP RIGHT BOTTOM LEFT.

Usage:

$ mandelbrot FILE <HEIGHTxWIDTH> TOP RIGHT BOTTOM LEFT

Example:

$ cargo build --release
$ target/release/mandelbrot mandel.png 3000x3000 2 2 -2 -2

Unit Circle Set

let mut z = c;
for i in 0..limit {
    z = z * z;
}

Mandelbrot Set

let mut z = Complex { re: 0.0, im: 0.0 };
for i in 0..limit {
    z = z * z + c;
}
