Enum ObjectSpec 

pub enum ObjectSpec {
    Template(Template),
    Column(String),
    Constant(String),
    TypedColumn {
        column: String,
        datatype: String,
    },
    LangColumn {
        column: String,

    },
    ConstantIri(String),
}

Specifies how the object of a triple should be produced from a data row

Variants

Template(Template)

Generate an IRI by rendering a template against the row

Column(String)

Use the column value as a plain string literal (xsd:string)

Constant(String)

Use a constant string — always the same value regardless of the row

TypedColumn

Use the column value as a typed literal

Fields

column: String

Column name containing the lexical value

datatype: String

Full XSD datatype IRI (e.g. "http://www.w3.org/2001/XMLSchema#integer")

LangColumn

Use the column value as a language-tagged literal; the language tag is taken from another column.

Fields

column: String

Column name containing the literal text

lang_column: String

Column name containing the BCP 47 language tag (e.g. "en")

LangFixed

Use the column value as a language-tagged literal with a fixed language

Fields

column: String

Column name containing the literal text

lang: String

BCP 47 language tag (e.g. "en")

ConstantIri(String)

Use a constant IRI value (no template substitution)

Trait Implementations

impl Clone for ObjectSpec

fn clone(&self) -> ObjectSpec

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ObjectSpec

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

Formats the value using the given formatter.

impl PartialEq for ObjectSpec

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