Get all objects from ets table
Background
I have an ets table with several objects in it. I want to, with 1 single operation, retrieve all keys and objects my table has.
Using match
I tried using match like this:
table = :ets.new(:table, [:public])
:ets.insert(table, [{:a, 0}, {:b, 1}, {:c, 2}])
:ets.match(table, '$1')
However it always returns empty.
What am I doing wrong?

@Fl4m3Ph03n1x :ets.tab2list is the best way to dump a whole table. Setting that aside though, is the code you posted supposed to show the issue? You aren’t inserting anything into the table.

for anyone (like me) wondering how this is done with :dets
:dets.foldl(fn elem, acc -> [elem | acc] end, [], t)

Btw, your mistake was that it is:
:ets.match(table, :"$1")`
