Module expression

Container

Mostly this shouldn’t be used, but it exists so that we don’t have to manually implement FromPyObject on all of ExprType

Expr

An Expr only contains a single value key, which leads to the actual expression, which is one of several types.

Functions

condition_to_rust

Lower an expression in condition position (if/while/ternary/assert tests): Python implicitly calls bool() on it. Boolean operators recurse into their operands and not negates a condition; comparisons already yield bool; anything else is wrapped in stdpython’s Truthy::is_truthy, giving Python’s truth table (empty string/collection and zero are false).
