Function load 

Source 
pub fn load(input: &str) -> Result<Document, Error>
Expand description

detect + parse. Process text and compact JSON are expanded (and laid out) into a BPMN or DMN document. Expansion does not apply the Camunda 8 deploy gate, so a draft still loads; run the lint crate to find what Zeebe would refuse.
