Struct FnDef 

pub struct FnDef {
    pub params: Vec<Arc<str>>,
    pub body: Node,
    pub span: Span,
}

A module-level def, callable from a macro body.

The body is the one the parser produced, before expansion: a compile-time call runs the definition as written. A def whose body calls a macro is therefore not callable at compile time, which is honest — the alternative is expansion order that depends on who calls what.

Fields

params: Vec<Arc<str>>

body: Node

span: Span
