shoji

A VBox/HBox layout library implemented in Rust. shoji allows your layout tree and it's calculations to be separate from your render tree. It's built for speed and style.

[dependencies]
shoji = "0.1"

Example

In shoji you build a tree of layout nodes each with a style that determines:

• direction child content flows
• margin/padding
• alignment
• etc.

use shoji::*;

fn main() -> Result<(), &'static str> {
    let mut shoji = Shoji::new();

    // Put together layout
    let top = shoji.new_node(LayoutStyle::default(),vec![]);

    let bottom_left = shoji.new_node(LayoutStyle::default(),vec![]);
    let bottom_right = shoji.new_node(LayoutStyle::default(),vec![]);

    let bottom = shoji.new_node(
        LayoutStyle { direction: Direction:LeftRight },
        vec![bottom_left, bottom_right],
    );

    let root = shoji.new_node(
        LayoutStyle { direction: Direction:TopDown },
        vec![top, bottom],
    );

    // Compute all layouts
    shoji.compute_layout(root, LayoutSize::new(100.0, 100.0))?;

    // Get the calculated layout
    dbg!(shoji.get_layout(top));
}

when you compute_layout to a constrained size, all layout nodes will have layout calculations with absolute values:
