Enum FnBody 

pub enum FnBody<'a> {
    Suite(&'a Suite<'a>),
    Expr(&'a Expression<'a>),
    Module(&'a [Statement<'a>]),
}

The body of a function-unit: a statement suite (def/method), a single expression (lambda), or a module’s top-level statement list (the synthetic <module> unit). Borrowed from the parsed Module.

Variants

Suite(&'a Suite<'a>)

A def/async def/method body — a statement suite.

Expr(&'a Expression<'a>)

A lambda body — a single expression.

Module(&'a [Statement<'a>])

The module’s top-level statement list — used by the synthetic <module> unit that scores import-time effects. The own-body walker treats this like a suite of statements but does NOT descend into nested def/class bodies (those are separate units), exactly matching the behaviour of walk_compound for nested functions.
