Yoga-rs

A Rust wrapper for Facebook's Yoga layout library.

You may also want to check out taffy (a revived fork of the abandoned stretch) as it is a pure Rust implementation.

Dependencies

• cargo
• rustc

Build

$ cargo build --release

Run Example

$ cargo run --release --example layout

Format Code

$ cargo +nightly fmt

Example Code

```rust

[macro_use]

extern crate yoga;

use yoga::prelude::*; use yoga::Node; use yoga::StyleUnit::{Auto, UndefinedValue};

fn main() { let mut node = Node::new();

let mut child = Node::new();
let mut other_child = Node::new();

node.insert_child(&mut child, 0);
node.insert_child(&mut other_child, 1);

style!(node,
    Margin(10 pt),
    MarginLeft(Auto),
    PaddingHorizontal(4 pt),
    Left(16 %),
    Bottom(UndefinedValue)
);

let child_styles = make_styles!(
    Width(32 pt),
    Height(32 pt),
    FlexGrow(1.0),
    Margin(Auto)
);

child.apply_styles(&child_styles);
other_child.apply_styles(&child_styles);

node.calculate_layout(512.0, 512.0, yoga::Direction::LTR);

println!("Layout is {:#?}", child.get_layout());

} ```

Testing

The unit tests are automatically generated based on upstream fixtures and should not be edited manually.

$ cargo test

To generate the test cases: Download the ChromeDriver binary and put it somewhere in your $PATH. Linux/MacOS example:

$ cp chromedriver /usr/local/bin

Then run the following

bash $ cd gentest $ bundle install # Install the required ruby gems $ ruby gentest/gentest.rb # Generate the tests $ cargo +nightly fmt # Format the tests for consistency
