Enum QueryTerm 

pub enum QueryTerm {
    Variable(String),
    Constant(String),
}

A term in a query atom — either a variable or a constant (IRI/literal)

Variants

Variable(String)

A variable (name without the ‘?’ prefix, stored as plain string)

Constant(String)

A constant IRI or literal

Implementations

impl QueryTerm

pub fn var(name: impl Into<String>) -> Self

pub fn constant(iri: impl Into<String>) -> Self

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

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

pub fn is_variable(&self) -> bool

Trait Implementations

impl Clone for QueryTerm

fn clone(&self) -> QueryTerm

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for QueryTerm

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

Formats the value using the given formatter.

impl Hash for QueryTerm

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 QueryTerm

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