Expand description
A context that can validate shared archive memory.
Shared pointers require this kind of context to validate.
Required methods
Claims count
shared bytes located offset
bytes away from base
.
Returns whether the bytes need to be checked.
Safety
The caller must guarantee that base
is inside the archive this context was created for.
Provided methods
Claims the memory referenced by the given relative pointer.
If the pointer needs to be checked, returns Some
with the pointer to check.
