Enum HRef 

pub enum HRef {
    Local(String),
    Remote(String),
}

An xlink:href reference to a GML object.

Distinguishes between local fragment references (same document) and remote URI references at the type level, keeping the # prefix as a serialization-only detail.

Examples

use egml_core::model::xlink::HRef;

// Both forms produce the same local reference
assert_eq!(HRef::from_local("#UUID_abc_def"), HRef::from_local("UUID_abc_def"));

let local: HRef = "#UUID_abc_def".parse().unwrap();
assert_eq!(local, HRef::from_local("UUID_abc_def"));
assert_eq!(local.local_id(), Some("UUID_abc_def"));
assert_eq!(local.to_string(), "#UUID_abc_def");

let remote: HRef = "https://example.com/geom".parse().unwrap();
assert_eq!(remote, HRef::Remote("https://example.com/geom".to_string()));
assert_eq!(remote.local_id(), None);
assert_eq!(remote.to_string(), "https://example.com/geom");

Variants

Local(String)

A fragment reference to an object in the same document. Stores the bare ID without the # prefix.

Remote(String)

A full URI reference to an external resource.

Implementations

impl HRef

pub fn from_local(id: impl Into<String>) -> HRef

Constructs a local fragment reference, stripping a leading # if present.

Accepts both raw xlink:href attribute values ("#UUID_abc") and bare GML ids ("UUID_abc"). The # prefix is added back on serialization.

pub fn from_local_id(id: Id) -> HRef

Constructs a local fragment reference from a GML Id.

pub fn from_remote(uri: impl Into<String>) -> HRef

Constructs a remote URI reference.

pub fn local_id(&self) -> Option<&str>

Returns the bare GML gml:id if this is a local fragment reference.

pub fn is_local(&self) -> bool

Returns true if this is a local fragment reference.
