Function literal
pub(super) fn literal(default: &str, dotted: &str) -> Result<String, Error>Expand description
Accepts a default only if it is a plain Python literal or the stub placeholder.
... is accepted when PyO3 renders an opaque Rust-expression default; the
committed stub can then use Python’s standard placeholder without copying a
Rust constant. Other non-literals (including an address-bearing object repr)
fail closed because they would make generated output unreproducible.
