Int

The Int keyword (with an uppercase I) is a case-sensitive reserved word. Both int and Int are lexed as the same integer-type token, but they are two distinct reserved spellings: neither may be used as an identifier.

Syntax & Example​

let total: Int = -5;
fn offset(x: Int): Int {
    return x + 1;
}

Use Cases​

  • Providing an alternative spelling for the integer type.
  • Matching naming conventions that prefer capitalized type names.
Case sensitivity

Keyword matching is case sensitive. int and Int are two distinct reserved words that map to the same integer-type token. int is not interchangeable with uint.
