Function parse_openapi_document 

pub fn parse_openapi_document(
    body: &[u8],
    document_origin: &Url,
) -> OpenApiParseOutcome

Classifies and reduces one repository- or host-retained document.

document_origin is used only to classify server metadata conservatively. It never grants authority, resolves references, performs I/O, or selects a request target. A runtime must authorize every selected URL independently.
