Enum web_sys::IdbCursorDirection

#[non_exhaustive]
#[repr(u32)]
pub enum IdbCursorDirection {
    Next = 0,
    Nextunique = 1,
    Prev = 2,
    Prevunique = 3,
}

The IdbCursorDirection enum.

This API requires the following crate features to be activated: IdbCursorDirection

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Next = 0

Nextunique = 1

Prev = 2

Prevunique = 3

Implementations

impl IdbCursorDirection

pub fn from_js_value(obj: &JsValue) -> Option<IdbCursorDirection>

Trait Implementations

impl Clone for IdbCursorDirection

fn clone(&self) -> IdbCursorDirection

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for IdbCursorDirection

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

Formats the value using the given formatter.

impl From<IdbCursorDirection> for JsValue

fn from(val: IdbCursorDirection) -> Self

Converts to this type from the input type.

impl FromWasmAbi for IdbCursorDirection

type Abi = u32

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

unsafe fn from_abi(val: u32) -> Self

Recover a Self from Self::Abi.

impl IntoWasmAbi for IdbCursorDirection

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 OptionFromWasmAbi for IdbCursorDirection

fn is_none(val: &u32) -> 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 IdbCursorDirection

fn none() -> Self::Abi

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

impl PartialEq for IdbCursorDirection

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
