Trevor Gross beb34db83d Split cast into cast and cast_lossy ... There is a difference in intent between wishing to cast and truncate the value, and expecting the input to be within range. To make this clear, add separate `cast_lossy` and `cast_from_lossy` to indicate what that truncation is intended, leaving `cast` and `cast_from` to only be casts that expected not to truncate. Actually enforcing this at runtime is likely to have a cost, so just `debug_assert!` that `cast` doesn't truncate.		2025-01-11 18:28:45 -05:00
