Detailed Description

Row-wise view of the vtable, for the completeness scan.

Reading a structure of function pointers through an array of function pointers is only defined through a union, so the scan uses one. The accompanying static assertion is what makes the view safe: it fails the build if the vendored table ever gains a member that is not a function pointer, rather than letting the scan silently misread it.

Invariant

Both members are exactly the same size.

Every member of the table is a function pointer.

Example:

ra8_esp_hosted_osi_view_t view = { .table = *table };
