Error code E0592

This error occurs when you defined methods or associated functions with same name.

Erroneous code example:

#![allow(unused)] fn main() { 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.

#![allow(unused)] fn main() { struct Foo; impl Foo { fn bar() {} } impl Foo { fn baz() {} // define with different name } }
