pub enum Reference<T: AsIri = IriBuf> {
    Id(T),
    Blank(BlankId),
    Invalid(String),
}

Expand description

Node reference.

Used to reference a node across a document or to a remote document. It can be an identifier (IRI), a blank node identifier for local blank nodes or an invalid reference (a string that is neither an IRI nor blank node identifier).

Variants

`Id(T)`

Node identifier, essentially an IRI.

`Blank(BlankId)`

Blank node identifier.

`Invalid(String)`

Invalid reference.

Implementations

source

impl<T: AsIri> Reference<T>

source

pub fn is_valid(&self) -> bool

Checks if this is a valid reference.

Returns true is this reference is a node identifier or a blank node identifier, false otherwise.

source

pub fn as_str(&self) -> &str

Get a string representation of the reference.

This will either return a string slice of an IRI, or a blank node identifier.

source

pub fn as_iri(&self) -> Option<Iri<'_>>

If the renference is a node identifier, returns the node IRI.

Returns None if it is a blank node reference.
