//! Check that `-A warnings` cli flag applies to non-lint warnings as well.
|
|
//!
|
|
//! This test tries to exercise that by checking that the "relaxing a default bound only does
|
|
//! something for `?Sized`; all other traits are not bound by default" non-lint warning (normally
|
|
//! warn-by-default) is suppressed if the `-A warnings` cli flag is passed.
|
|
//!
|
|
//! Take special note that `warnings` is a special pseudo lint group in relationship to non-lint
|
|
//! warnings, which is somewhat special. This test does not exercise other `-A <other_lint_group>`
|
|
//! that check that they are working in the same way, only `warnings` specifically.
