Struct VisibleRange 

pub struct VisibleRange {
    pub start_index: usize,
    pub end_index: usize,
    pub overscan: usize,
    pub count: usize,
}

Describes the visible range of items in a virtualized list.

Contains the start and end indices of the visible viewport along with the overscan and total count used to compute the rendered index set. This type is passed to custom range extractors.

Fields

start_index: usize

The first visible item index (inclusive).

end_index: usize

The last visible item index (inclusive).

overscan: usize

The number of extra items beyond the viewport.

count: usize

The total number of items in the dataset.

Trait Implementations

impl Clone for VisibleRange

fn clone(&self) -> VisibleRange

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for VisibleRange

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

Formats the value using the given formatter.

impl PartialEq for VisibleRange

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