Hi,
when compiling following code I get following error:
use std::num;
struct vec2d { a:f32, b:f32 }
impl num::Zero for vec2d {
fn zero() -> vec2d {
vec2d{a:0.0, b:0.0}
}
fn is_zero(&self) -> bool {
self.a==0.0 && self.b==0.0
}
}
test.rs:4:1: 12:2 error: failed to find an implementation of trait
std::ops::Add<vec2d,vec2d> for vec2d
test.rs:4 impl num::Zero for vec2d {
test.rs:5 fn zero() -> vec2d {
test.rs:6 vec2d{a:0.0, b:0.0}
test.rs:7 }
test.rs:8
test.rs:9 fn is_zero(&self) -> bool {
Would you know why the Add trait seems to be a requirement for implementing
the zero trait.
cheers,
Rémi
