    // Required methods
    fn destructure_size(size: Size) -> (u32, u32);
    fn create_size(primary: u32, secondary: u32) -> Size;

}

Helper trait that describes a linear layout orientation.

Required Associated Types

type Secondary: SecondaryAlignment + Alignment

Secondary alignment that will be applied to all the views

Required Methods

fn destructure_size(size: Size) -> (u32, u32)

Destructure Size into (primary_size, secondary_size)

fn create_size(primary: u32, secondary: u32) -> Size

Create a Size from primary and secondary size values

fn compute_offset( &self, bounds: Rectangle, size: Size, previous: Rectangle, n: usize, count: usize, ) -> Point

Computes translation for the next view.

Provided Methods

fn place( &self, view: &mut dyn View, size: Size, previous: Rectangle, n: usize, count: usize, ) -> Rectangle

Place view

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.
