Struct abi_stable::nonexhaustive_enum::UnwrapEnumError

#[must_use]
#[repr(transparent)]pub struct UnwrapEnumError<N> {
    pub non_exhaustive: N,
    // some fields omitted
}

An error for a situation where a NonExhaustive<> could not be unwrapped into the enum because the discriminant wasn't valid in this context (likely because it is from a newer version of the library).

Fields

non_exhaustive: N

This field is either a NonExhaustive<> or a DiscrAndEnumInfo<>

Implementations

impl<N> UnwrapEnumError<N>

#[must_use]pub fn into_inner(self) -> N

Gets the non_exhaustive field.

pub fn into_boxed(self) -> RBoxError where
    N: NonExhaustiveSharedOps,
