Struct Magic

source

pub struct Magic<T: 'static> { /* private fields */ }

Expand description

Runtime memory error checking to help catch errors that C code is prone to. Can probably drop once C interop is removed.

Prefer to place Magic struct fields as the first field. This causes the Magic field to be dropped first when dropping the enclosing struct, which validates that the Magic is valid before running Drop implementations of the other fields.

T should be the type of the struct that contains the Magic.
