Expand description
Return the length of a tuple.
§Examples
Usage:
assert_eq!(().len(), 0);
assert_eq!((1i8,).len(), 1);
assert_eq!((1u16, 2u64).len(), 2);
assert_eq!((1i8, 2usize, 3i64).len(), 3);§Supported tuple lengths
Possible length 8, 16, 32, 64. By default the selected operations are implemented to tuples upto a length of 8 elements.
§Features
You can specify the length: features = [“tup_len_16”] or features = [“tup_len_32”] or features = [“tup_len_64”].
