// If you're reading the implementation, before proceeding further, you should

// RETURN TYPES
|
||
|
|
//
|
||
|
|
// Though Bind()'s result is meant to be stored in a Callback<> type, it
|
||
|
|
// cannot actually return the exact type without requiring a large amount
|
||
|
|
// of extra template specializations. The problem is that in order to
|
||
|
|
// discern the correct specialization of Callback<>, Bind would need to
|
||
|
|
// unwrap the function signature to determine the signature's arity, and
|
||
|
|
// whether or not it is a method.
|
||
|
|
//
|
||
|
|
// Each unique combination of (arity, function_type, num_prebound) where
|
||
|
|
// function_type is one of {function, method, const_method} would require
|
||
|
|
// one specialization. We eventually have to do a similar number of
|
||
|
|
// specializations anyways in the implementation (see the Invoker<>,
|
||
|
|
// classes). However, it is avoidable in Bind if we return the result
|
||
|
|
// via an indirection like we do below.
|
||
|
|
//
|
||
|
|
// TODO(ajwong): We might be able to avoid this now, but need to test.
|
||
|
|
//
|
||
|
|
// It is possible to move most of the COMPILE_ASSERT asserts into BindState<>,
|
||
|
|
// but it feels a little nicer to have the asserts here so people do not
|
||
|
|
// need to crack open bind_internal.h. On the other hand, it makes Bind()
|
||
|
|
// harder to read.
