Every trait defines a type, but because the size of trait implementors isn't fixed, this type has no compile-time size. Therefore, all accesses to trait types must be through pointers. If you encounter this error you should try to avoid dereferencing the pointer. - - You can read more about trait objects in the Trait Objects section of the Reference: https://doc.rust-lang.org/reference/types.html#trait-objects - -error: aborting due to 3 previous errors - -Some errors have detailed explanations: E0033, E0038, E0423. -For more information about an error, try `rustc --explain E0033`. -- cgit v1.2.3
