This would be very useful for For example: struct Foo(Cow<'static, [u32]>);
impl Foo {
// Initialize with heap-allocated data at runtime.
fn heap(data: Vec<u32>) -> Self {
Foo(Cow::Owned(data))
}
// Initialize with static data at compile-time.
const fn static(data: &'static [u32]) -> Self {
Foo(Cow::Borrowed(data))
}
// Access the data, possibly at compile-time, possibly at runtime.
const fn data(&self) -> &[u32] {
match self.0 {
Cow::Borrowed(slice) => slice,
Cow::Owned(vec) => vec.as_slice(),
}
}

This change `const`-qualifies many methods on Vec and String, notably `as_slice`, `as_str`, `len`. These changes are made behind the unstable feature flag `const_vec_string_slice` with the following tracking issue: rust-lang#129041
