A Value
represents a single self-contained Rust value.
A Value
can either refer to a block of memory inside an allocation (ByRef
) or to a primitve
value held directly, outside of any allocation (ByVal
). For ByRef
-values, we remember
whether the pointer is supposed to be aligned or not (also see Place).
For optimization of a few very common cases, there is also a representation for a pair of
primitive values (ScalarPair
). It allows Miri to avoid making allocations for checked binary
operations and fat pointers. This idea was taken from rustc's codegen.
