error[E0015]: cannot call non-const fn `Vec::<u32>::len` in constant functions
--> $DIR/issue-94675.rs:9:27
|
LL | self.bar[0] = baz.len();
| ^^^^^
|
= note: calls in constant functions are limited to constant functions, tuple structs and tuple variants
error[E0277]: the trait bound `Vec<usize>: ~const IndexMut<usize>` is not satisfied
--> $DIR/issue-94675.rs:9:9
|
LL | self.bar[0] = baz.len();
| ^^^^^^^^^^^ vector indices are of type `usize` or ranges of `usize`
|
= help: the trait `~const IndexMut<usize>` is not implemented for `Vec<usize>`
note: the trait `IndexMut<usize>` is implemented for `Vec<usize>`, but that implementation is not `const`
