To deference a pointer, it must be correctly aligned for
T
. Since there's no alignment check at runtime or enforcement by the type system, this code must useread_unaligned
to read the integer's bytes out of the slice. Code like this tends to work fine on x86 because it generally supports unaligned memory access, but may fault on other architectures.This problem can be demonstrated by running
cargo miri test
before this PR.
