Struct mozjs::jsapi::mozilla::GenericErrorResult

#[repr(C)]
pub struct GenericErrorResult<E> {
    pub mErrorValue: E,
    pub _phantom_0: PhantomData<UnsafeCell<E>>,
}

A type that auto-converts to an error Result. This is like a Result without a success type. It’s the best return type for functions that always return an error–functions designed to build and populate error objects. It’s also useful in error-handling macros; see MOZ_TRY for an example.

Fields

mErrorValue: E

_phantom_0: PhantomData<UnsafeCell<E>>

Trait Implementations

impl<E> Clone for GenericErrorResult<E>

where E: Clone,

fn clone(&self) -> GenericErrorResult<E>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<E> Debug for GenericErrorResult<E>

where E: Debug,

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

Formats the value using the given formatter.

impl<E> PartialEq for GenericErrorResult<E>

where E: PartialEq,

fn eq(&self, other: &GenericErrorResult<E>) -> 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<E> Copy for GenericErrorResult<E>

where E: Copy,

impl<E> StructuralPartialEq for GenericErrorResult<E>
