Contract

  1. uuid.Validate returns nil for valid UUID string in standard 8-4-4-4-12 format
  2. uuid.Validate returns error for malformed UUID string with invalid length or characters
  3. uuid.ParseBytes parses byte slice of valid UUID string and returns matching UUID struct
  4. uuid.ParseBytes returns error and Nil UUID when given invalid byte slice
  5. uuid.ParseBytes parses 32-character hex byte slice without dashes successfully
