An atom is to be enclosed in single quotes (’) if it does not begin with a lower-case letter or if it contains other characters than alphanumeric characters, underscore (_), … Status must be a non-negative integer, a string, or the atom abort. Halts the Erlang runtime system. Has no return value. Depending on Status: integer() The runtime system exits with the integer value Status as status code to the calling environment (operating system). string() An erlang crash dump is produced with Status as slogan, and then Converting strings to atoms safely. If your elixir system accepts any outside inputs and takes any part of those outside inputs and calls String.to_atom with the input as an argument then your elixir system is subject to a denial of service attack.

Instead we have to choose to pay a small cost for runtime typing, or to restrict the values coming from Erlang. Restricting Values Two: Atoms. An atom is equivalent to an enumeration type in C + +, but the value of an atom in Erlang is itself. Atoms are a string that starts with "lowercase letters," but if you use single quotes, the name of the atom doesn't matter, and a lot of the tricks come out. 2020-06-25 Erlang's Atoms come to mind when I think of this, to quote the Erlang Documentation: 3.3 Atom. An atom is a literal, a constant with name.

When processing lists it is often convenient to be able to refer to the first element of the list Atoms. Erlang atoms look much like their Elixir counterparts without the colon ( : ).

The return value is expressed in bytes. Let’s now look at a slightly different version of the function: 2> erlang:memory(atom_used). 187410. This variant returns the amount of memory used for the atom table itself plus the amount of memory of atom string space actually used.
