Crate xsd_types

source ·
Expand description

This crate aims at providing safe representations of XSD built-in data types.

§Usage

For each XSD datatype, this library provides two families of types: one representing the lexical space of the datatype (see the lexical module), and one representing the value space of the datatype (see the value module).

For instance, assume we wish to store the lexical representation of an XSD decimal datatype value. We can use the lexical::Decimal type (or its owned variant, lexical::DecimalBuf)

let string = "3.141592653589793";

// Parse the lexical representation (lexical domain).
let lexical_repr = xsd_types::lexical::Decimal::new(string).unwrap();

// Interprets the lexical representation (value domain).
use xsd_types::lexical::LexicalFormOf;
let value_repr: xsd_types::Decimal = lexical_repr.try_as_value().unwrap();

Of course it is possible to parse the value directly into the value domain using FromStr:

let value_repr: xsd_types::Decimal = "3.141592653589793".parse().unwrap();

§Any value

The Value type provides a simple way to represent any XSD value.

use xsd_types::{XSD_DATE, Datatype, Value};
let dt = Datatype::from_iri(XSD_DATE).unwrap();
let value: Value = dt.parse("1758-12-25").unwrap(); // Halley is back!
