The compiler team's explanation
This error occurs when you defined methods or associated functions with same name.
Erroneous code example:
struct Foo;
impl Foo {
fn bar() {} // previous definition here
}
impl Foo {
fn bar() {} // duplicate definition here
}A similar error is E0201. The difference is whether there is one declaration block or not. To avoid this error, you must give each fn a unique name.
struct Foo;
impl Foo {
fn bar() {}
}
impl Foo {
fn baz() {} // define with different name
