The borrowed value to mutate.

Return:

Raw TVMFFIAny carrying a replacement, the unchanged marker, or Error.

FStructuralVarRemapGet var_remap_get = nullptr

Look up the replacement for a variable identity.

Param mutator:

The active structural mutator.

Param var:

The borrowed variable identity to look up.

Return:

Raw TVMFFIAny carrying the owning replacement, FFI None on a miss, or Error.

FStructuralVarRemapSet var_remap_set = nullptr

Record the replacement for a variable identity.
