you can regard trait as interface as ts.but it is more flexiable.
pub struct Animal {
name:String
}
pub trait Action {
fn say() ;
fn getName -> String；
}
impl Action for Animal {
fn say(){
},
fn getName() ->String{
}
}
and you can set default implement for tait
such as
pub trait Action {
fn say(){
},
fn getName -> String；
}
impl Action for Animal {
fn getName() ->String{
}
}
seond powerful function
pub trait Action<T,U> {
fn say(){
},
fn getName -> String；
}
pub trait2 Action<T,U> {
fn say(){
},
fn getName -> String；
}
fn main(ff:impl trait<String,String> + trait2<String,String> ) {
}
fn main<T:trait<String,String> + trait2<String,String>>(ff:T){
}
fn main<T,U>(ff:T)
where
T:trait<String,String> + trait2<String,String>
{
}
the three methods are equal
