export type ets:type/1

[mheiber]

Is your feature request related to a problem? Please describe.

We have code that abstracts over ets functions, which have ets:type/1 as a parameter type.
Our workaround of having our own type that repeats the definition of ets:type/1 is awkward and not forwards-compatible.

Describe the solution you'd like

Export ets:type/1 or an alias, if a different name is desired

Describe alternatives you've considered

workaround described above

Additional context

In general, when a type is mentioned in exported functions of a module, it makes sense to me to either:

• expose the type
• if implementation-hiding is necessary, create an opaque wrapper. Expose the opaque wrapper and use the opaque wrapper in specs for exported functions

related issues:

• export opaque wrapper for re:mp/0 #4969
• export supervisor types: restart/0, mfargs/0 shutdown/0 #4970
