Is there a way to disable this linter.
I tried to modify some code But I end with some lifetime issue
is there a way to disable it.
rigth now I am not very consider about performance

My code kind of like this. should be normal code???

Using format_args is already suspicious and I wouldn't call that "normal code" (i.e. I've never used format_args! directly). Also you don't really gain anything from putting the if let+formatting inside of the format! macro. I'd argue this just makes the code more complicated to read.

So I would do one of two things:

1. If you don't care about (minor) perf optimizations, pull the if let in front of the formatting

   let schema_str = if let Some(schema) = schema {
       format!("{}.", self.quote(schema),)
   } else { /*...*/ }
   let sql = format!("ALTER TABLE {}{} UPDATE ", schema_str, self.quote(table_name));

2. To not create an unnecessary string you could add more format args, e.g. if you want to have one branch that adds a . and another that shouldn't:

   format!("foo {}{} {} bar",
      self.quote(schema),
      if some_condition { "." } else { "" },
      self.quote(table_name),
   )

If you just want to disable it, you can put #[allow(clippy::format_in_format_args)] before the let mut sql = assignment: Playground. This applies to all lints.

@flip1995 ok thanks.
