error: const `impl` for trait `A` which is not marked with `#[const_trait]`
|
|
--> $DIR/const-impl-requires-const-trait.rs:6:12
|
|
|
|
|
LL | impl const A for () {}
|
|
| ^ this trait is not `const`
|
|
|
|
|
= note: marking a trait with `#[const_trait]` ensures all default method bodies are `const`
|
|
= note: adding a non-const method body in the future would be a breaking change
|
|
help: mark `A` as `#[const_trait]` to allow it to have `const` implementations
|
|
|
|
|
LL | #[const_trait] pub trait A {}
