Enum PlainTermEncodingField 

pub enum PlainTermEncodingField {
    TermType,
    Value,
    DataType,
    LanguageTag,
}

Represents the fields of the PlainTermEncoding.

Variants

TermType

Indicates the type of RDF term.

Value

Contains the lexical value of an RDF term.

DataType

Holds the data type of RDF literal, including simple literals and language-tagged literals. If an RDF term has a language tag, the datatype must contain rdf:langString.

This filed should be null for named nodes and blank nodes.

LanguageTag

Contains an optional language tag for language-tagged literals.

This field should be null for named nodes, blank nodes, and literals without a language tag.

Trait Implementations

impl Clone for PlainTermEncodingField

fn clone(&self) -> PlainTermEncodingField

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PlainTermEncodingField

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

Formats the value using the given formatter.

impl PartialEq for PlainTermEncodingField

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