Enum Redefinition 

pub enum Redefinition {
    Error,
    LastWins,
}

What two definitions of one name in one scope and namespace mean.

Examples

use resolve_lang::{Policy, Redefinition};

assert_eq!(Policy::python().redefinition(), Redefinition::LastWins);
assert_eq!(Policy::kraken().redefinition(), Redefinition::Error);

Variants

Error

A duplicate definition is an error; the first one is kept.

LastWins

A later definition replaces an earlier one (Python def f twice). With Hoist::AfterDecl each definition is visible from its own declaration on.
