Enum SparqlOpArity 

pub enum SparqlOpArity {
    Nullary,
    Fixed(usize),
    OneOf(Vec<SparqlOpArity>),
    Variadic,
}

Defines the arity of a SPARQL operation. In other words, the number of arguments that the ScalarSparqlOp has.

Variants

Nullary

No arguments.

Fixed(usize)

A fixed number of arguments.

SparqlOpArity::Fixed(0) is equivalent to SparqlOpArity::Nullary.

OneOf(Vec<SparqlOpArity>)

One of the given SparqlOpArity.

Variadic

Any number of arguments (including zero).

Implementations

impl SparqlOpArity

pub fn type_signature<TEncoding: TermEncoding>( &self, encoding: &TEncoding, ) -> TypeSignature

Returns a TypeSignature for the given SparqlOpArity.

Trait Implementations

impl Clone for SparqlOpArity

fn clone(&self) -> SparqlOpArity

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SparqlOpArity

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

Formats the value using the given formatter.

impl Hash for SparqlOpArity

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 PartialEq for SparqlOpArity

fn eq(&self, other: &SparqlOpArity) -> 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.
