Enum cosmwasm_std::Never

pub enum Never {}

Never can never be instantiated. This can be used in places where we want to ensure that no error is returned, such as the ibc_packet_receive entry point.

In contrast to Empty, this does not have a JSON schema and cannot be used for message and query types.

Once the ! type is stable, this is not needed anymore. See https://github.com/rust-lang/rust/issues/35121.
