Fields

start_row: usize

First visible row

end_row: usize

Last visible row (exclusive)

render_start_row: usize

Implementations

impl VisibleGridRange

pub fn cells_to_render(&self, total_items: usize) -> Vec<GridCell>

Get all cells that should be rendered

pub fn should_render_cell(&self, row: usize, col: usize) -> bool

Check if a cell should be rendered

Trait Implementations

impl Clone for VisibleGridRange

fn clone(&self) -> VisibleGridRange

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for VisibleGridRange

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for VisibleGridRange

fn eq(&self, other: &VisibleGridRange) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
