Hi,
is there a way to write something as follow in rust?
class matrix {
...
float& Get(int r, int c) { return this.data[r + c*4]; }
}
matrix m;
m.Get(0, 1) = 42.;
in trust, my struct matrix would have a method called Get, but what would
it return?
struct Mat {
data:[float, ..16]
}
impl Mat {
pub fn Get(&mut self, r:int, c:int) -> &mut float {
&self.data[r+c*4]
}
}
I get error messages about lifetime or about mutability
est.rs:107:8: 107:24 error: mismatched types: expected `&mut float` but
found `&float` (values differ in mutability)
test.rs:107 &self.data[r*4+c]
^~~~~~~~~~~~~~~~
cheers,
Remi
