Enum OutKind 

#[non_exhaustive]
pub enum OutKind {
    Text,
    Int,
    Bool,
}

The kind of value an engine member writes back through a by-reference argument.

Some members report their result in the return value and their explanation in out-parameters: an expression check answers pass or fail, then says what was wrong and where. Reading only the return value throws that away.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Text

A string the engine allocates, VT_BYREF | VT_BSTR.

Int

A 32-bit integer, VT_BYREF | VT_I4.

Bool

A boolean, VT_BYREF | VT_BOOL.
