Enum PatternTerm 

pub enum PatternTerm {
    Iri(String),
    Literal(String),
    Variable(String),
    BlankNode(String),
}

A position in a triple pattern – can be an IRI, a plain literal, a blank node, or a variable (placeholder for pattern matching).

Variants

Iri(String)

Literal(String)

Variable(String)

BlankNode(String)

Implementations

impl PatternTerm

pub fn is_variable(&self) -> bool

Returns true when this term is a variable (used during template instantiation).

pub fn variable_name(&self) -> Option<&str>

Returns the variable name if this is a Variable variant.

Trait Implementations

impl Clone for PatternTerm

fn clone(&self) -> PatternTerm

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PatternTerm

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

Formats the value using the given formatter.

impl Eq for PatternTerm

impl Hash for PatternTerm

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 PatternTerm

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