Match Spec

[Vladimir Sekissov]

Good day,

You can use erlang:match_spec_test/3. The only problem - match spec
is parsed every time in this BIF.

7> MS = ets:fun2ms(fun ({A, B}) -> A end).
[{{'$1','$2'},[],['$1']}]
8> erlang:match_spec_test([], MS, table).
{ok,false,[],[]}
9> erlang:match_spec_test({a, b}, MS, table).
{ok,a,[],[]}
