}Expand description
How a primitive arranges its slots. See the module docs.
Required Methods§
fn name(&self) -> &'static str
Provided Methods§
fn readable_column(&self) -> Option<Length>
fn readable_column(&self) -> Option<Length>
The readable column this arrangement keeps what it holds in, when it is one: a page’s measure, which a bar at the foot of the column stands in too.
fn leading(&self) -> Side
fn leading(&self) -> Side
The side the arrangement leads on: where lead reserves its gutter. A row written
right to left leads on the right.
fn settle(&mut self, _allocated: Size<f32>, _resolved: &Resolved) -> bool
fn settle(&mut self, _allocated: Size<f32>, _resolved: &Resolved) -> bool
Decide the arrangement from the allocated size. Returns whether the styles must be computed again.
fn items(&mut self, _count: usize)
fn items(&mut self, _count: usize)
How many slots the container holds, told before each layout: a layout that arranges by count (a grid that keeps no empty columns) reads it.
Whether slot index is not shown in the current arrangement.
