}Expand description
Recursively compute a representational hash for a type.
ReprHash::repr_hash is a recursive function that computes
representation information about a zero-copy type. It is used to
check that the the alignment and the representation data
of the data being deserialized.
More precisely, at each call a zero-copy type look at offset_of,
assuming that the type is stored at that offset in the structure,
hashes in the padding necessary to make offset_of a multiple of
core::mem::align_of the type, hashes in the type size, and
finally increases offset_of by core::mem::size_of the type.
