What does this Zig snippet output?

1const std = @import("std");
2const Vec2 = struct {
3    x: f32,
4    y: f32,
5    fn dot(self: Vec2, other: Vec2) f32 {
6        return self.x * other.x + self.y * other.y;
7    }
8};
9pub fn main() void {
10    const a = Vec2{ .x = 3.0, .y = 4.0 };
11    const b = Vec2{ .x = 1.0, .y = 2.0 };
12    std.debug.print("{d:.0}\n", .{a.dot(b)});
13}
