Conceptually `Digest()` is just a parsed string wrapper. Many cases want to get access to the full value without allocating, and the introduction of the type was a regression from that point of view in 0.7. Luckily, we can change our internals in such a way that it's safe to add the impl. Do that by holding onto the full value, with a duplicate small boxed str for the algorithm only in the degenerate case that it's an unknown type. If we had this it would have made containers/bootc#800 less likely. Signed-off-by: Colin Walters <[email protected]>
