Two associated items (like methods, associated types, associated functions,
etc.) were defined with the same identifier.
Erroneous code example:
#![allow(unused)]
fn main() {
struct Foo(u8);
impl Foo {
fn bar(&self) -> bool { self.0 > 5 }
fn bar() {}
}
trait Baz {
type Quux;
fn baz(&self) -> bool;
}
impl Baz for Foo {
type Quux = u32;
fn baz(&self) -> bool { true }
fn baz(&self) -> bool { self.0 > 5 }
type Quux = u32;
}
}
ⓘ
Note, however, that items with the same name are allowed for inherent impl
blocks that don't overlap:
#![allow(unused)]
fn main() {
struct Foo<T>(T);
impl Foo<u8> {
fn bar(&self) -> bool { self.0 > 5 }
}
impl Foo<bool> {
fn bar(&self) -> bool { self.0 }
}
}
