Struct kernel::CommandReturn[][src]

pub struct CommandReturn(_);

Possible return values of a command driver method, as specified in TRD104.

This is just a wrapper around SyscallReturn since a command driver method may only return primitve integer types as payload.

It is important for this wrapper to only be constructable over variants of SyscallReturn that are deemed safe for a capsule to construct and return to an application (e.g. not SubscribeSuccess). This means that the inner value must remain private.
