Luke HindsWhat is Self, not in a philosophical sense, but what is Self in rusts world?
We create a simple Struct which defines a bool and an int.
struct RandomInfo {
some_bool: bool,
some_int: i32,
}
We can then implement the struct as a type:
impl RandomInfo {
fn new() -> RandomInfo {
RandomInfo {
some_bool: true,
some_int: 42,
}
}
}
However, we don't actually need to specify the type, the compiler is able to infer the type itself, so we can instead use Self
impl RandomInfo {
fn new() -> Self {
Self {
some_bool: true,
some_int: 42,
}
}
}
Putting it all together
struct RandomInfo {
some_bool: bool,
some_int: i32,
}
impl RandomInfo {
fn new() -> Self {
Self {
some_bool: true,
some_int: 42,
}
}
}
fn main() {
let info = RandomInfo::new();
println!("some_bool: {}", info.some_bool);
println!("some_int: {}", info.some_int);
}
