There has been a change a while ago that tried to unify the
ArrayBufferView
interface, but it turned out that the changes there are unsafe. In particular:Array<T>
must not expose.buffer
since it can resize automatically, leading to use-after-free scenarios in the worst case.Array<T>
does not have a.byteLength
property.The only sensible solution there is to use distinct
@unsafe
fields for the ABV interface, with actual implementations providing safe getters.Original breaking PR: #865
