Enum TermRef 

pub enum TermRef<'a> {
    NamedNode(&'a str),
    BlankNode(&'a str),
    Literal(&'a str, Option<&'a str>, Option<&'a str>),
    Variable(&'a str),
}

Zero-copy RDF term reference that avoids allocations

This provides efficient operations on RDF terms without copying data

Variants

NamedNode(&'a str)

BlankNode(&'a str)

Literal(&'a str, Option<&'a str>, Option<&'a str>)

Variable(&'a str)

Implementations

impl<'a> TermRef<'a>

pub fn from_named_node(node: &'a NamedNode) -> Self

Create a term reference from a named node

pub fn from_blank_node(node: &'a BlankNode) -> Self

Create a term reference from a blank node

pub fn from_literal(literal: &'a Literal) -> Self

Create a term reference from a literal

pub fn as_str(&self) -> &'a str

Get the string representation of this term

pub fn to_owned(&self) -> Result<Term, OxirsError>

Convert to an owned Term (allocating if necessary)

pub fn is_named_node(&self) -> bool

Returns true if this is a named node

pub fn is_blank_node(&self) -> bool

Returns true if this is a blank node

pub fn is_literal(&self) -> bool

Returns true if this is a literal

pub fn is_variable(&self) -> bool

Returns true if this is a variable

Trait Implementations

impl<'a> Clone for TermRef<'a>

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

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for TermRef<'a>

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

Formats the value using the given formatter.

impl<'a> Display for TermRef<'a>

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

Formats the value using the given formatter.

impl<'a> Hash for TermRef<'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> PartialEq for TermRef<'a>

fn eq(&self, other: &TermRef<'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.
