pub enum RowHeights<'a> {
Uniform(f32),
Variable {
revision: u64,
height: &'a dyn Fn(usize) -> f32,
},
}Expand description
How tall rows are.
Variants§
Uniform(f32)
Variable
height(i) for every row; called for all rows only when revision or the row count
changes, and for the rows in VirtualList::changed_rows. Non-finite or negative heights
count as 0, heights are capped at 10 000 points.
