🔬This is a nightly-only experimental API. (
core_io_internals)Returns a lower bound on the number of elements this container-like item
contains.
For example, an array
[u8; 12] could return any value between 0 and
12 inclusively as a correct implementation. Read moreSource§impl<T> SizedTypeProperties for T
