Trait rome::graph::LiteralPtr

pub trait LiteralPtr<'g> {
    type DatatypePtr: DatatypePtr<'g> + PartialEq;
    fn as_str(&self) -> &str;
    fn datatype(&self) -> Self::DatatypePtr;
    fn datatype_str(&self) -> &str;
    fn language(&self) -> Option<&str>;

    fn to_resource<B, I>(&self) -> Resource<'g, B, I, Self>
    where
        Self: Clone,
        B: BlankNodePtr<'g>,
        I: IRIPtr<'g>,
    { ... }
}

A trait for a pointers to literals in graphs.

The lifetime of iterals is tied to the graph to which they belong. A literal always has a datatype. It has an optional language.

Associated Types

type DatatypePtr: DatatypePtr<'g> + PartialEq

The type of pointer for the datatype of the literal.

Required Methods

fn as_str(&self) -> &str

Get the value of the literal (without datattype or language)

fn datatype(&self) -> Self::DatatypePtr

Get the datatype of the literal.

fn datatype_str(&self) -> &str

Get the datatype of the literal as a string.

fn language(&self) -> Option<&str>

Get the language of the literal.

Provided Methods

fn to_resource<B, I>(&self) -> Resource<'g, B, I, Self> where
    Self: Clone,
    B: BlankNodePtr<'g>,
    I: IRIPtr<'g>, 

Wrap the literal in a Resource. This is convenient when passing the literal as an object in a triple.
