sophia_term 0.5.2

This crate is part of Sophia, an RDF and Linked Data toolkit in Rust.

Terms are the building blocks of an RDF graph. There are four types of terms: IRIs, blank nodes (BNode for short), literals and variables.

NB: variable only exist in generalized RDF.

This module defines a generic type Term which can be derived differently depending on your needs.

• RefTerm<'a> (alias of Term<&'a str>) should be used for very short-lived terms, i.e. terms that live less than 'a, which is the lifetime of their underlying text.

• BoxTerm (alias of Term<Box<str>>) should be used when the term may outlive the text used to create it.

• RcTerm (alias of Term<Rc<str>>) should also be used for long-lived terms, especially if they need to be cloned multiple times. The use of Rc prevents the duplication of the underlying text, while ensuring that it is cleaned when appropriate.

• ArcTerm (alias of Term<Arc<str>>) should be used when, additionally, terms need to be sent to other threads.

• StaticTerm (alias of Term<&'static str>) is a special case of RefTerm` where the underlying text is a static string. Those terms can live as long as the program runs, and be cloned and sent without any restriction.

• MownTerm (alias of `Term<MownStr<'a>>) should be used in situations where some terms can borrow their data, while others need to own it.
