Struct Grid 

pub struct Grid { /* private fields */ }

A sparse grid of string cells.

Sparse because an Office-like document is mostly empty: a million-cell sheet with 900k empty cells must not allocate a million Strings.

Implementations

impl Grid

pub fn new() -> Self

pub fn set(&mut self, cell: CellRef, value: String)

pub fn get(&self, cell: CellRef) -> Option<&str>

pub fn is_empty(&self) -> bool

pub fn len(&self) -> usize

pub fn count_in(&self, range: CellRange) -> usize

Number of populated cells inside a range.

pub fn used_rows(&self) -> usize

Highest populated row + 1.

pub fn used_cols(&self) -> usize

Highest populated column + 1.

pub fn fill_down( &mut self, from: CellRef, count: usize, max_rows: usize, ) -> Result<usize, FcError>

Fills count rows below a cell with the same value.

Auto-fill. Bounded by max_rows so a malformed argument cannot spin allocating millions of cells.

impl Grid

pub fn js_new() -> Grid

pub fn js_set(&mut self, row: usize, col: usize, value: String)

pub fn js_get(&self, row: usize, col: usize) -> Option<String>

pub fn js_len(&self) -> usize

pub fn js_used_rows(&self) -> usize

pub fn js_used_cols(&self) -> usize

pub fn js_fill_down( &mut self, row: usize, col: usize, count: usize, max_rows: usize, ) -> Result<usize, JsValue>

pub fn js_count_in(&self, r1: usize, c1: usize, r2: usize, c2: usize) -> usize

count populated cells inside a range.

Trait Implementations

impl Clone for Grid

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Grid

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

Formats the value using the given formatter.

impl Default for Grid

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Grid

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<Grid> for JsValue

fn from(value: Grid) -> Self

Converts to this type from the input type.

impl FromWasmAbi for Grid

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 Grid

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 Grid

type Abi = u32

Same as RefFromWasmAbi::Abi

type Anchor = RcRef<Grid>

Same as RefFromWasmAbi::Anchor

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

Same as RefFromWasmAbi::ref_from_abi

impl OptionFromWasmAbi for Grid

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 Grid

fn none() -> Self::Abi

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

impl RefFromWasmAbi for Grid

type Abi = u32

The Wasm ABI type references to Self are recovered from.

type Anchor = RcRef<Grid>

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

Recover a Self::Anchor from Self::Abi.

impl RefMutFromWasmAbi for Grid

type Abi = u32

Same as RefFromWasmAbi::Abi

type Anchor = RcRefMut<Grid>

Same as RefFromWasmAbi::Anchor

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

Same as RefFromWasmAbi::ref_from_abi

impl Serialize for Grid

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl SupportsConstructor for Grid

impl SupportsInstanceProperty for Grid

impl SupportsStaticProperty for Grid

impl TryFromJsValue for Grid

fn try_from_js_value(value: JsValue) -> Result<Self, JsValue>

Performs the conversion.

fn try_from_js_value_ref(value: &JsValue) -> Option<Self>

Performs the conversion.

impl VectorFromWasmAbi for Grid

fn vector_into_abi(vector: Box<[Grid]>) -> Self::Abi

impl WasmDescribe for Grid

fn describe()

impl WasmDescribeVector for Grid
