Struct Variable

pub struct Variable<'a> {
    pub name: &'a str,
}

A SPARQL variable.

The default string formatter is returning a SPARQL compatible representation.

use rio_api::model::Variable;

assert_eq!(
    "?foobar",
    Variable { name: "foobar" }.to_string()
)

Using it requires to enable the generalized feature.

Fields

name: &'a str

The name of the variable itself.

Trait Implementations

impl<'a> Clone for Variable<'a>

fn clone(&self) -> Variable<'a>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for Variable<'a>

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

Formats the value using the given formatter.

impl<'a> Display for Variable<'a>

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

Formats the value using the given formatter.

impl<'a> From<Variable<'a>> for GeneralizedTerm<'a>

fn from(other: Variable<'a>) -> GeneralizedTerm<'a>

Converts to this type from the input type.

impl<'a> Hash for Variable<'a>

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<'a> Ord for Variable<'a>

fn cmp(&self, other: &Variable<'a>) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl<'a> PartialEq for Variable<'a>

fn eq(&self, other: &Variable<'a>) -> 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.

impl<'a> PartialOrd for Variable<'a>

fn partial_cmp(&self, other: &Variable<'a>) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
