impl<T: Float> Deref for Finite<T>

§

impl<T: Float + FromJSValConvertible<Config = ()>> FromJSValConvertible for Finite<T>

§

type Config = ()

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

unsafe fn from_jsval( cx: *mut JSContext, value: HandleValue<'_>, option: () ) -> Result<ConversionResult<Finite<T>>, ()>

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<T: Float + MallocSizeOf> MallocSizeOf for Finite<T>

source§

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<T: PartialEq + Float> PartialEq<Finite<T>> for Finite<T>

source§

fn eq(&self, other: &Finite<T>) -> bool

This method tests for self and other values to be equal, and is used by ==.
1.0.0 · source§

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

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