// Oh dear! It seems we got a little carried away making const u8 values.
|
||
|
|
// * const means constant (cannot be changed)
|
||
|
|
// * u8 means unsigned (cannot be negative), 8-bit integer
|
||
|
|
//
|
||
|
|
// Hint 1: Use 'var' for values that can change.
|
||
|
|
// Hint 2: Use enough bits to hold the value you want:
|
||
|
|
// u8 255
|
||
|
|
// u16 65,535
|
||
|
|
// u32 4,294,967,295
|
||
|
|
// Hint 3: Use 'i' (e.g. 'i8', 'i16') for signed integers.
