Struct FnLayout 

Source 
pub struct FnLayout<S, P> { /* private fields */ }
Expand description

A LayoutAlgorithm made of two closures.

layout builds one of these. It exists as a named type rather than a pair of boxes so that the trait has something to be implemented on — and so a caller who wants to keep the layout around can name its type.

Trait Implementations§

Source§

impl<S, P> LayoutAlgorithm for FnLayout<S, P>
where S: Fn(&Subviews<'_>, Proposal) -> (f64, f64) + Send + Sync + 'static, P: Fn(&Subviews<'_>, Rect, Proposal) + Send + Sync + 'static,

Source§

fn size_that_fits( &self, subviews: &Subviews<'_>, proposal: Proposal, ) -> (f64, f64)

How big this layout wants to be, given what the parent offers.
Source§

fn place_subviews( &self, subviews: &Subviews<'_>, bounds: Rect, proposal: Proposal, )

Where each child goes, inside bounds.
