It took me a few attempts to get the for loop right, but here you go.
pub trait Base {
fn do_base(&self);
}
struct TestBase;
impl Base for TestBase {
fn do_base(&self) {
println!("ici");
}
}
trait GenericFn {
fn do_generic(&self, base: &Base);
}
struct DoGenericFn;
impl GenericFn for DoGenericFn {
fn do_generic(&self, base: &Base) {
base.do_base();
}
}
struct ToTestStr {
vec_gen: ~[~Base],
}
impl ToTestStr {
fn testgencall<T: GenericFn>(&self, gen: &T) {
for ref base in self.vec_gen.iter() {
gen.do_generic(**base);
}
}
}
#[main]
fn main() {
let testbase = TestBase;
let test = ToTestStr {vec_gen: ~[~testbase as ~Base],};
let gen = DoGenericFn;
test.testgencall(&gen);
}
