Struct CellRange 

pub struct CellRange {
    pub start_row: usize,
    pub start_col: usize,
    pub end_row: usize,
    pub end_col: usize,
    /* private fields */
}

A rectangular selection, always stored normalized: start is the top-left (row-major minimum) and end the bottom-right, whichever corner the user dragged from.

Fields

start_row: usize

start_col: usize

end_row: usize

end_col: usize

Implementations

impl CellRange

pub fn from_corners(a: CellRef, b: CellRef) -> Self

Normalizes a possibly-inverted drag.

Inversion is the normal case, not an error: dragging up-and-left from the anchor produces an inverted range by definition. Normalizing here means every downstream consumer can assume ordering.

pub fn single(cell: CellRef) -> Self

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

pub fn row_count(&self) -> usize

pub fn col_count(&self) -> usize

pub fn cell_count(&self) -> u64

Total cell count, saturating. WASM is a 32-bit platform, so a select-all on a large sheet can overflow usize; saturating is the honest answer because a number too large to count is not an actionable error.

pub fn with_anchor(self, cell: CellRef) -> Self

A range with an explicit anchor, defaulting to the top-left corner.

pub fn anchor(&self) -> CellRef

The anchor cell.

pub fn extend_to(&self, cell: CellRef) -> Self

Extends to include cell, keeping the original anchor. This is shift-arrow behaviour: focus moves, the anchor does not.

pub fn iter_cells(&self) -> Vec<CellRef>

The cells, in row-major order.

impl CellRange

pub fn js_from_corners(r1: usize, c1: usize, r2: usize, c2: usize) -> CellRange

pub fn js_single(row: usize, col: usize) -> CellRange

pub fn js_to_array(&self) -> Vec<u32>

pub fn js_cell_count(&self) -> u64

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

pub fn js_cells(&self) -> Vec<u32>

Flat [row, col, ...] coordinates in row-major order.

Trait Implementations

impl Clone for CellRange

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for CellRange

impl Debug for CellRange

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

impl Eq for CellRange

impl From<CellRange> for JsValue

fn from(value: CellRange) -> Self

Converts to this type from the input type.

impl FromWasmAbi for CellRange

type Abi = u32

The Wasm ABI type that this converts from when coming back out from the ABI boundary.

unsafe fn from_abi(js: u32) -> Self

Recover a Self from Self::Abi.

impl IntoWasmAbi for CellRange

type Abi = u32

The Wasm ABI type that this converts into when crossing the ABI boundary.

fn into_abi(self) -> u32

Convert self into Self::Abi so that it can be sent across the wasm ABI boundary.

impl LongRefFromWasmAbi for CellRange

type Abi = u32

Same as RefFromWasmAbi::Abi

type Anchor = RcRef<CellRange>

Same as RefFromWasmAbi::Anchor

unsafe fn long_ref_from_abi(js: Self::Abi) -> Self::Anchor

Same as RefFromWasmAbi::ref_from_abi

impl OptionFromWasmAbi for CellRange

fn is_none(abi: &Self::Abi) -> bool

Tests whether the argument is a “none” instance. If so it will be deserialized as None, and otherwise it will be passed to FromWasmAbi.

impl OptionIntoWasmAbi for CellRange

fn none() -> Self::Abi

Returns an ABI instance indicating “none”, which JS will interpret as the None branch of this option.

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

Equality operator ==.

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

impl RefFromWasmAbi for CellRange

type Abi = u32

The Wasm ABI type references to Self are recovered from.

type Anchor = RcRef<CellRange>

The type that holds the reference to Self for the duration of the invocation of the function that has an &Self parameter. This is required to ensure that the lifetimes don’t persist beyond one function call, and so that they remain anonymous.

unsafe fn ref_from_abi(js: Self::Abi) -> Self::Anchor

type Abi = u32

Same as RefFromWasmAbi::Abi
