Enum RdfNode 

pub enum RdfNode {
    Uri(String),
    BlankNode(String),
    Literal {
        value: String,
        language: Option<String>,
        datatype: Option<String>,
    },
}

Variants

Uri(String)

A named node (IRI/URI).

BlankNode(String)

A blank node with a local identifier.

Literal

A literal value with optional language tag or datatype.

Fields

value: String

The literal value.

language: Option<String>

Optional language tag (e.g., “en”, “ja”).

datatype: Option<String>

Optional datatype URI.

Implementations

impl RdfNode

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

Creates a new URI node.

pub fn blank(id: impl Into<String>) -> Self

Creates a new blank node.

pub fn literal(value: impl Into<String>) -> Self

Creates a new plain literal.

pub fn literal_with_lang( value: impl Into<String>, lang: impl Into<String>, ) -> Self

Creates a new literal with a language tag.

pub fn typed_literal( value: impl Into<String>, datatype: impl Into<String>, ) -> Self

Creates a new typed literal.

pub const fn is_uri(&self) -> bool

Returns true if this is a URI node.

pub const fn is_blank(&self) -> bool

Returns true if this is a blank node.

pub const fn is_literal(&self) -> bool

Returns true if this is a literal.

pub fn bf_class(class_name: &str) -> Self

Creates a BIBFRAME class URI.

pub fn bflc_class(class_name: &str) -> Self

Creates a BFLC class URI.

Trait Implementations

impl Clone for RdfNode

fn clone(&self) -> RdfNode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RdfNode

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

Formats the value using the given formatter.

impl Eq for RdfNode

impl PartialEq for RdfNode

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