// The `dbg` macro generates a literal with the name of the current file, so
|
||
|
|
// we need to ensure the lint is not emitted in this case.

// Clippy sets `-Zflatten_format_args=no`, which changes the default behavior of how format args
|
||
|
|
// are lowered and only that one has this non-macro span. Adding the flag makes it repro on
|
||
|
|
// godbolt and shows a root context span for the file name string.
