Struct RowWindow 

pub struct RowWindow {
    pub total_rows: usize,
    pub offset: usize,
}

Windowed-row mode: the grid presents total_rows virtual rows (scrollbar, row numbers, hit-testing, selection all speak the virtual index space) while data.rows holds only a resident window of them starting at offset. The host pages rows in/out with GridState::set_row_window as the user scrolls, keeping memory O(window) for arbitrarily large sets. Sorting and filtering are disabled while a window is active — the grid only sees a slice of the data, so a resident-only sort would lie.

Fields

total_rows: usize

Total rows in the virtual set.

offset: usize

Virtual index of data.rows[0].

Trait Implementations

impl Clone for RowWindow

fn clone(&self) -> RowWindow

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for RowWindow

impl Debug for RowWindow

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

Formats the value using the given formatter.

impl Eq for RowWindow

impl PartialEq for RowWindow

fn eq(&self, other: &RowWindow) -> 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.
