Enum OMMaybeForeign

pub enum OMMaybeForeign<'o, I> {
    OM(I),
    Foreign {
        encoding: Option<Cow<'o, str>>,
        value: Cow<'o, str>,
    },
}

Either an OpenMath Expression or an OMFOREIGN.

Generic over the non-OMFOREIGN-case, so it can be used in both OpenMath and OM

Variants

OM(I)

Foreign

If $A$ is not an OpenMath object, then $\mathrm{foreign}(A)$ is an OpenMath foreign object. An OpenMath foreign object may optionally have an encoding field which describes how its contents should be interpreted.

Fields

encoding: Option<Cow<'o, str>>

value: Cow<'o, str>

Trait Implementations

impl<'o, I: Clone> Clone for OMMaybeForeign<'o, I>

fn clone(&self) -> OMMaybeForeign<'o, I>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'o, I: Debug> Debug for OMMaybeForeign<'o, I>

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

Formats the value using the given formatter.

impl<'o, I: Hash> Hash for OMMaybeForeign<'o, I>

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<I: OMSerializable> OMOrForeign for &OMMaybeForeign<'_, I>

fn om_or_foreign( self, ) -> Either<impl OMSerializable, (Option<impl Display>, impl Display)>

converts this into an Either(crate::either::Either)

impl<'o, I: PartialEq> PartialEq for OMMaybeForeign<'o, I>

fn eq(&self, other: &OMMaybeForeign<'o, I>) -> 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.
