Validates IRI reference.

This validator corresponds to RiReferenceStr and RiReferenceString types.

Examples

This type can have an IRI reference (which can be absolute or relative).

use iri_string::{spec::UriSpec, validate::iri_reference};
assert!(iri_reference::<UriSpec>("https://user:pass@example.com:8080").is_ok());
assert!(iri_reference::<UriSpec>("https://example.com/").is_ok());
assert!(iri_reference::<UriSpec>("https://example.com/foo?bar=baz").is_ok());
assert!(iri_reference::<UriSpec>("https://example.com/foo?bar=baz#qux").is_ok());
assert!(iri_reference::<UriSpec>("foo:bar").is_ok());
assert!(iri_reference::<UriSpec>("foo:").is_ok());
// `foo://.../` below are all allowed. See the crate documentation for detail.
assert!(iri_reference::<UriSpec>("foo:/").is_ok());
assert!(iri_reference::<UriSpec>("foo://").is_ok());
assert!(iri_reference::<UriSpec>("foo:///").is_ok());
assert!(iri_reference::<UriSpec>("foo:////").is_ok());
assert!(iri_reference::<UriSpec>("foo://///").is_ok());
assert!(iri_reference::<UriSpec>("foo/bar").is_ok());
assert!(iri_reference::<UriSpec>("/foo/bar").is_ok());
assert!(iri_reference::<UriSpec>("//foo/bar").is_ok());
assert!(iri_reference::<UriSpec>("#foo").is_ok());

Some characters and sequences cannot used in an IRI reference.

use iri_string::{spec::UriSpec, validate::iri_reference};
// `<` and `>` cannot directly appear in an IRI reference.
assert!(iri_reference::<UriSpec>("<not allowed>").is_err());
// Broken percent encoding cannot appear in an IRI reference.
assert!(iri_reference::<UriSpec>("%").is_err());
assert!(iri_reference::<UriSpec>("%GG").is_err());
