oxsdatatypes is an implementation of some XML Schema Definition Language Datatypes. Its main aim is to ease the implementation of SPARQL and XPath.

Usage example:

use std::str::FromStr;
use oxsdatatypes::Decimal;

assert!(Decimal::from_str("22.2").unwrap() > Decimal::from_str("21").unwrap());

Each datatype is represented by a Rust struct.

Each datatype provides:

  • FromStr implementation to parse a datatype string serialization following its lexical mapping.
  • Display implementation to serialize a datatype following its canonical mapping.
  • is_identical_with method following its identity relation.
  • PartialEq, and Eq if possible, implementations following its equality relation.
  • PartialOrd, and Ord if possible, implementations following its order relation.
  • From and TryFrom implementations to implement XPath casting.
  • Various methods implementing XPath functions.
  • from_be_bytes and to_be_bytes methods for serialization.
