4322 :: How does one declare byte array constants?

• vsajip (orginal) [2018-10-19T15:17:11+02:00] view original

  For example, a lookup table of bytes might be declared as

  
  const LOOKUP_TABLE: array[4, byte] = [1, 2, 3, 4]
  Run

  but that gives a type mismatch as the numbers are interpreted as int. Of course one can do [byte(1), byte(2), byte(3), byte(4)], but the numbers are quite lost in the noise! Is there a better way?

  You can specify just the first member:

  const LOOKUP_TABLE: array[4, byte] = [byte(1), 2, 3, 4]
  Run

  In any case, you have to indicate at least that the first value is a byte. For instance:

  
  const LOOKUP_TABLE: array[4, byte] = [1'u8, 2, 3, 4]
  Run

  or more elegant

  
  const LOOKUP_TABLE: array[4, byte] = [byte 1, 2, 3, 4]
  Run
