Struct Range 

pub struct Range {
    pub start: Position,
    pub end: Position,
}

A range of text in document order — start precedes or equals end. Built in document order by Dom::selection_range, which accepts any two positions and sorts them; Range::ordered_unchecked trusts the caller’s order.

Use Range::is_collapsed to detect zero-length ranges (the “caret” case).

v1 note: sorting requires document-order comparison, which needs the Dom. If you already know your two positions are in order, use the struct literal directly (or Range::ordered_unchecked); otherwise call Dom::selection_range to get the normalized range for the current Selection.

Fields

start: Position

end: Position

Implementations

impl Range

pub fn ordered_unchecked(start: Position, end: Position) -> Self

Construct a range assuming the caller already knows the positions are in document order. Never fails; if you pass positions in the wrong order the resulting Range is unusable for paint / copy but will still compile.

For a DOM-ordered normalization, use Dom::selection_range.

pub fn is_collapsed(&self) -> bool

true iff start == end — zero-length range (caret position; no highlighted text).
