. You have to concatenate the null byte <<0>>
to a string that you want to see its inner binary representation like in the following way…@enforce_keys [<keys>]
while defining the struct…@enforce_keys
is a simple compile-time guarantee to aid developers when building structs. It is not enforced on updates and it does not provide any sort of value-validation. The above warning is from the ORIGINAL DOCUMENTATIONfunction_exported?/3
to achieve this…String.split/2 function
. But you can also pass a pattern to match that over and over and splitting the string whenever it matches the pattern.!
, two minus — symbols -
and a asterisk *

and last
for lists
gets you the element first and last respectively in the given list. Similarly, the strings give you the first and last graphemes
