Trait Implementations

impl From<(&Field, Box<dyn Array>)> for FFIArrowArray

fn from(value: (&Field, Box<dyn Array>)) -> Self

Converts to this type from the input type.

impl From<FFIArrowArray> for JsValue

fn from(value: FFIArrowArray) -> Self

Converts to this type from the input type.

impl FromWasmAbi for FFIArrowArray

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 FFIArrowArray

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 FFIArrowArray

type Abi = u32

Same as RefFromWasmAbi::Abi

type Anchor = RcRef<FFIArrowArray>

Same as RefFromWasmAbi::Anchor

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

Same as RefFromWasmAbi::ref_from_abi

impl OptionFromWasmAbi for FFIArrowArray

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 FFIArrowArray

fn none() -> Self::Abi

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

impl RefFromWasmAbi for FFIArrowArray

type Abi = u32

The Wasm ABI type references to Self are recovered from.

type Anchor = RcRef<FFIArrowArray>

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 FFIArrowArray

type Abi = u32

Same as RefFromWasmAbi::Abi

type Anchor = RcRefMut<FFIArrowArray>

Same as RefFromWasmAbi::Anchor

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

Same as RefFromWasmAbi::ref_from_abi

impl TryFrom<FFIArrowArray> for Box<dyn Array>

type Error = GeoArrowError

The type returned in the event of a conversion error.

fn try_from(ffi_array: FFIArrowArray) -> Result<Self>

Performs the conversion.

impl TryFromJsValue for FFIArrowArray

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 FFIArrowArray

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

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

impl VectorIntoJsValue for FFIArrowArray

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

impl VectorIntoWasmAbi for FFIArrowArray

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

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