impl PartialEq<Term> for Term

fn eq(&self, other: &Term) -> bool

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

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

This method tests for !=.

impl StructuralEq for Term

impl StructuralPartialEq for Term

impl TTerm for Term

fn kind(&self) -> TermKind

Returns the kind of this term (IRI, literal, blank node, variable).

fn value_raw(&self) -> RawValue<'_>

Return the "value" of this term, possibly split in two substrings. The second part might only be non-empty if this term is an IRI reference.

fn datatype(&self) -> Option<SimpleIri<'_>>

fn as_dyn(&self) -> &dyn TTerm

This method ensures that all implementations of TTerm can be turned into a trait object.

fn value(&self) -> MownStr<'_>

Return the "value" of this term, which depends on its kind: * for an IRI reference, its value; * for a literal, its lexical value; * for a blank node, its local identifier; * for a variable, its name.

fn is_absolute(&self) -> bool

All terms are absolute, except for: * relative IRI references, * literals whose datatype is a relative IRI reference.

type Error = SophiaToOxigraphConversionError

The error type produced when failing to copy a given term

fn try_copy<T: ?Sized>(other: &T) -> Result<Self, Self::Error> where
    T: TTerm, 

Try to copy term into an instance of this type.
