Structs & Unions
- Names of user defined types like structs and unions must start with an uppercase letter.
- Structs and unions can be nested.
- Initialization follows C rules with
{ }.
- Unlike C it’s possible to reassign the value of a struct or union with
{ } as well.
import std::io;
union Point
{
// Nested struct
struct
{
int x, y;
}
int[2] v;
}
fn void main()
{
Point p = { 2, 3 };
io::printfn("Point: %d, %d", p.x, p.y);
// Reassign the p value using a literal and named arguments:
p = { .v = { 5, -1 } };
io::printfn("Point: %d, %d", p.x, p.y);
}
