Struct RangeRef 

pub struct RangeRef {
    pub sheet: String,
    pub start: Address,
    pub end: Address,
}

A resolved rectangular range: a sheet (folded name) and an inclusive, top-left-first corner pair.

Range-node compression hinges on this being a single value regardless of area: membership of a CellRef is an O(1) rectangle test (RangeRef::contains), so finding the formula cells that read a changed cell through a range costs one test per distinct range, never one per cell in the range.

Fields

sheet: String

The target sheet’s name, simple-case-folded.

start: Address

Top-left corner (minimum row, minimum column).

end: Address

Bottom-right corner (maximum row, maximum column).

Implementations

impl RangeRef

pub fn contains(&self, cell: &CellRef) -> bool

Whether cell lies inside this range (same sheet, within the inclusive rectangle). The membership test behind range-node compression.

Trait Implementations

impl Clone for RangeRef

fn clone(&self) -> RangeRef

Returns a duplicate of the value.

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

impl Ord for RangeRef

fn cmp(&self, other: &RangeRef) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.
