Tuple expressions
A tuple expression constructs tuple values. The syntax for tuple expressions is a parenthesized, comma separated list of expressions. 1-ary tuple expressions require a comma after their tuple initializer operand to be disambiguated with a parenthetical expression.
Tuple expressions without any tuple initializer operands produce the unit tuple value.
Examples:
| Expression | Type |
|---|---|
() |
() |
(1_u32,) |
(u32,) |
(1_u32, Option::Some(3_u8)) |
(u32, Option<u8>) |
(True, False, 'abc') |
(bool, bool, felt252) |
