// An anonymous struct value LITERAL (not to be confused with a
|
|
// struct TYPE) uses '.{}' syntax:
|
|
//
|
|
// .{
|
|
// .center_x = 15,
|
|
// .center_y = 12,
|
|
// .radius = 6,
|
|
// }
|
|
//
|
|
// These literals are always evaluated entirely at compile-time.
|
|
// The example above could be coerced into the i32 variant of the
|
|
// "circle struct" from the last exercise.
|
|
//
|
|
// Or you can let them remain entirely anonymous as in this
|
|
// example:
|
|
//
|
|
// fn bar(foo: anytype) void {
|
|
// print("a:{} b:{}\n", .{foo.a, foo.b});
|
|
// }
|
|
//
|
|
// bar(.{
|
|
// .a = true,
|
|
// .b = false,
|
|
// });
|
|
//
|
|
// The example above prints "a:true b:false".
|
|
//
