Enum IdbCursorDirection 

#[non_exhaustive]
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_str(s: &str) -> Option<IdbCursorDirection>

Convert a string to this enum variant.

pub fn to_str(&self) -> &'static str

Convert this enum variant to its string representation.

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

Convert a JsValue (if it’s a string) to this enum variant.

Trait Implementations

impl BatchableResult for IdbCursorDirection

fn try_placeholder(_: &mut Runtime) -> Option<Self>

Returns Some(placeholder) for opaque types that can be batched, None for types that require flushing to get the actual value.

impl BinaryDecode for IdbCursorDirection

fn decode(decoder: &mut DecodedData<'_>) -> Result<Self, DecodeError>

impl BinaryEncode for IdbCursorDirection

fn encode(self, encoder: &mut EncodedData)

impl Clone for IdbCursorDirection

fn clone(&self) -> IdbCursorDirection

Returns a duplicate 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 EncodeTypeDef for IdbCursorDirection

fn encode_type_def(buf: &mut Vec<u8>)

Encode this type’s definition into the buffer. For primitives, this is just the TypeTag byte. For callbacks, this includes param count, param types, and return type.

impl From<IdbCursorDirection> for JsValue

fn from(val: IdbCursorDirection) -> Self

Converts to this type from the input type.

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.
