Macro namespace

macro_rules! namespace {
    ($iri_prefix:expr, $($suffix:ident),*; $($r_id:ident, $r_sf:expr),*) => { ... };
    ($iri_prefix:expr, $($suffix:ident),*) => { ... };
}

Create a “namespace module” defining a set of terms within a given IRI space.

Tests

This macro also create a test module to check that all created IRIs are valid.

This allows to skip those checks at runtime, keeping the initialization of the namespace fast.

Example

/// An example namespace module
pub mod ex {
  namespace! {
    "http://example.org/ns#",
    Foo,
    Bar,
    Baz
  }
}

assert_eq!(ex::Foo, IriRef::new_unchecked("http://example.org/ns#Foo"));
assert_eq!(ex::Bar, IriRef::new_unchecked("http://example.org/ns#Bar"));
