Trait RoundTree

pub trait RoundTree: TraverseTree {
    // Required methods
    fn get_unrounded_layout(&self, node_id: NodeId) -> Layout;
    fn set_final_layout(&mut self, node_id: NodeId, layout: &Layout);
}

Trait used by the round_layout method which takes a tree of unrounded float-valued layouts and performs rounding to snap the values to the pixel grid.

As indicated by it’s dependence on TraverseTree, it required full recursive access to the tree.

Required Methods

fn get_unrounded_layout(&self, node_id: NodeId) -> Layout

Get the node’s unrounded layout

fn set_final_layout(&mut self, node_id: NodeId, layout: &Layout)

Get a reference to the node’s final layout

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
