Struct ObTypeIndex 

pub struct ObTypeIndex(/* private fields */);

Mapping from object types to numerical indices.

Like MorTypeIndex, this struct just compensates for the lack of hash maps with arbitrary keys in JavaScript.

Implementations

impl ObTypeIndex

pub fn new() -> Self

Creates a new object type index.

pub fn contains_key(&self, x: &ObType) -> bool

Returns whether the object type is set.

pub fn get(&self, x: &ObType) -> Option<usize>

Gets the index of an object type, if set.

pub fn insert(&mut self, x: ObType, i: usize)

Sets the index of an object type.

Trait Implementations

impl Clone for ObTypeIndex

fn clone(&self) -> ObTypeIndex

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Default for ObTypeIndex

fn default() -> ObTypeIndex

Returns the “default value” for a type.

impl From<ObTypeIndex> for JsValue

fn from(value: ObTypeIndex) -> Self

Converts to this type from the input type.

impl FromWasmAbi for ObTypeIndex

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 ObTypeIndex

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 ObTypeIndex

type Abi = u32

Same as RefFromWasmAbi::Abi

type Anchor = RcRef<ObTypeIndex>

Same as RefFromWasmAbi::Anchor

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

Same as RefFromWasmAbi::ref_from_abi

impl OptionFromWasmAbi for ObTypeIndex

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 ObTypeIndex

fn none() -> Self::Abi

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

impl RefFromWasmAbi for ObTypeIndex

type Abi = u32

The Wasm ABI type references to Self are recovered from.

type Anchor = RcRef<ObTypeIndex>

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 ObTypeIndex

type Abi = u32

Same as RefFromWasmAbi::Abi

type Anchor = RcRefMut<ObTypeIndex>

Same as RefFromWasmAbi::Anchor

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

Same as RefFromWasmAbi::ref_from_abi

impl TryFromJsValue for ObTypeIndex

type Error = JsValue

The type returned in the event of a conversion error.

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

Performs the conversion.

impl VectorFromWasmAbi for ObTypeIndex

type Abi = <Box<[JsValue]> as FromWasmAbi>::Abi

unsafe fn vector_from_abi(js: Self::Abi) -> Box<[ObTypeIndex]>

impl VectorIntoJsValue for ObTypeIndex

fn vector_into_jsvalue(vector: Box<[ObTypeIndex]>) -> JsValue

impl VectorIntoWasmAbi for ObTypeIndex

type Abi = <Box<[JsValue]> as IntoWasmAbi>::Abi

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