Function emit 

pub fn emit(graph: &TypeGraph) -> String

Emit a complete Rust source file from the given TypeGraph.

The returned string is formatted with prettyplease and is guaranteed to be parseable by syn::parse_file.

xs:choice types (IR crate::ir::types::EnumDef) that appear as struct field values are automatically wrapped in crate::common::ChoiceWrapper<T> so that quick-xml + serde can round-trip them correctly.

Panics

Panics if the generated token stream cannot be parsed by syn. This indicates a bug in the emitter (not in user input).
