Struct ElementRef 

pub struct ElementRef {
    pub document: Option<String>,
    pub id: String,
}

A reference to one element, optionally inside a named document.

Cross-document referencing is the shared shape behind BCF viewpoint components and ICDD linkset endpoints. Both name a document and an element within it; only the vocabulary differs.

Fields

document: Option<String>

The document the element lives in, when the reference crosses one.

None means “the current document” — an intra-document reference.

id: String

The element’s identifier within that document, verbatim.

Kept as an opaque string on purpose: an IFC GlobalId, an ICDD URI and a BCF component GUID are not the same syntax, and normalising them here would lose information that only the owning standard can interpret.

Implementations

impl ElementRef

pub fn local(id: impl Into<String>) -> Self

A reference within the current document.

pub fn in_document(document: impl Into<String>, id: impl Into<String>) -> Self

A reference into another document.

pub fn is_cross_document(&self) -> bool

Whether this reference crosses a document boundary.
