[swift-users] Mapping C semantics to Swift

[Ken Burgett]

I would like to know if a struct in Swift has any guarantee of 
contiguity, like a struct in C.  I am attempting to port a C program 
that makes many assumptions about the underlying semantics of C structs, 
and does things like overlaying an array over the struct using a cast, 
and then performs and cryptographic hashing of the entire struct by 
treating it as an array.

1.  I a Swift struct contiguous?

2.  If 1 above is true, can I somehow cast an array over the struct?
