Another (IMHO more elegant) solution would be a union, where you lay your char array over your struct. Up0TrueDown Radoslav Marinov10 年多前in reply toChester Gillon Intellectual1000points Since the pointers are ...

5. Which of the following is an incorrect syntax for pointer to structure?(Assuming struct temp{int b;}*my_struct;)a) *my_struct.b = 10; b) (*my_struct).b = 10; c) my_struct->b = 10; d) Both *my_struct.b = 10; and (*my_struct).b = 10; View Answer...
Normal Zig structs and unions do not guarantee size or field order. Zig is allowed to insert secret fields. So, for every normal struct that the code does a @ptrCast to or a @fieldParentPtr, insert a secret first field which has 4 bytes ...

Since this is used in very minimal number of cases I propose that we document that conversion from unsafe.Pointer to *struct{} and backwards is always valid. That is way we can always get a type which satisfies *T contract and is safe to use, because dereferencing *struct{} gives you ...
