struct

Declares a C struct layout for FFI: extern struct Name { field: type, … };.

The struct can be passed to and returned from C functions by value; a returned struct is read with .field. Field types are C scalar names such as int32, int or float. There are no Coil structs: use class.

extern struct Point {
    x: int32,
    y: int32,
};
