Implementations

impl IDBCursorDirection

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

Trait Implementations

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<(), Error>

Formats the value using the given formatter.

impl Default for IDBCursorDirection

fn default() -> IDBCursorDirection

Returns the “default value” for a type.

impl FromJSValConvertible for IDBCursorDirection

type Config = ()

Optional configurable behaviour switch; use () for no configuration.

unsafe fn from_jsval( cx: *mut JSContext, value: Handle<'_, Value>, _option: (), ) -> Result<ConversionResult<IDBCursorDirection>, ()>

Convert val to type Self. Optional configuration of type T can be passed as the option argument. If it returns Err(()), a JSAPI exception is pending. If it returns Ok(Failure(reason)), there is no pending JSAPI exception.

impl FromStr for IDBCursorDirection

type Err = ()

The associated error which can be returned from parsing.

fn from_str( s: &str, ) -> Result<IDBCursorDirection, <IDBCursorDirection as FromStr>::Err>

Parses a string s to return a value of this type.

impl MallocSizeOf for IDBCursorDirection

fn size_of(&self, ops: &mut MallocSizeOfOps) -> usize

Measure the heap usage of all descendant heap-allocated structures, but not the space taken up by the value itself.

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.

impl ToJSValConvertible for IDBCursorDirection

unsafe fn to_jsval(&self, cx: *mut JSContext, rval: MutableHandle<'_, Value>)

Convert self to a JSVal. JSAPI failure causes a panic.

impl Traceable for IDBCursorDirection

unsafe fn trace(&self, tracer: *mut JSTracer)

Trace self.

impl Copy for IDBCursorDirection
