Enum script::dom::bindings::conversions::ConversionResult

pub enum ConversionResult<T> {
    Success(T),
    Failure(Cow<'static, str>),
}

An enum to better support enums through FromJSValConvertible::from_jsval.

Variants

Success(T)

Everything went fine.

Failure(Cow<'static, str>)

Conversion failed, without a pending exception.

Implementations

impl<T> ConversionResult<T>

pub fn get_success_value(&self) -> Option<&T>

Returns Some(value) if it is ConversionResult::Success.

Trait Implementations

impl<T> Clone for ConversionResult<T>where
    T: Clone,

fn clone(&self) -> ConversionResult<T>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T> Debug for ConversionResult<T>where
    T: Debug,

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

Formats the value using the given formatter.

impl<T> PartialEq<ConversionResult<T>> for ConversionResult<T>where
    T: PartialEq<T>,

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

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

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.

impl<T> Eq for ConversionResult<T>where
    T: Eq,

impl<T> StructuralEq for ConversionResult<T>

impl<T> StructuralPartialEq for ConversionResult<T>
