-# `diagnostic_namespace`
-
-The tracking issue for this feature is: [#111996]
-
-[#111996]: https://github.com/rust-lang/rust/issues/111996
-
-------------------------
-
-The `diagnostic_namespace` feature permits customization of compilation errors.
-
-## diagnostic::on_unimplemented
-
-With [#114452] support for `diagnostic::on_unimplemented` was added.
-
-When used on a trait declaration, the following options are available:
-
-* `message` to customize the primary error message
-* `note` to add a customized note message to an error message
-* `label` to customize the label part of the error message
-
-The attribute will hint to the compiler to use these in error messages:
-```rust
-// some library
-#![feature(diagnostic_namespace)]
-
-#[diagnostic::on_unimplemented(
-    message = "cannot insert element",
-    label = "cannot be put into a table",
-    note = "see <link> for more information about the Table api"
-)]
-pub trait Element {
-    // ...
-}
-```
