Enum ReturnGuard

Source

pub enum ReturnGuard {
    None,
    Unconstructed(Identifier),
    Constructed {
        plain: Identifier,
        any_return: Identifier,
    },
}

Variants§

§

None

There were no conditionals on the path to this return statement.

§

Unconstructed(Identifier)

There was a chain of conditionals on the path to this return statement, and they are true iff this Identifier is true.

§

Constructed

There was a chain of conditionals on the path to this return statement.`

Fields

§plain: Identifier

True iff the conditionals on the path to this return statement are true.

§any_return: Identifier

True iff any of the guards to return statements so far encountered are true. We cache this to guard asserts against early returns.
