An associated const was implemented when another trait item was expected. Erroneous code example:
trait Foo { type N; } struct Bar; impl Foo for Bar { const N : u32 = 0; // error: item `N` is an associated const, which doesn't match its // trait `<Bar as Foo>` }
Please verify that the associated const wasn't misspelled and the correct trait was implemented. Example:
struct Bar; trait Foo { type N; } impl Foo for Bar { type N = u32; // ok! }
Or:
struct Bar; trait Foo { const N : u32; } impl Foo for Bar { const N : u32 = 0; // ok! }
