You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: schedule.rs
    path of file: ./repos/bevy/crates/bevy_ecs/src/schedule
    
    the code of the file until where you have to start completion: use std::{
    collections::BTreeSet,
    fmt::{Debug, Write},
};

#[cfg(feature = "trace")]
use 
    
    pub fn print_ignored_ambiguities(&self, components: &Components) {
        let mut message =
            "System order ambiguities caused by conflicts on the following types are ignored:\n"
                .to_string();
        for id in self.iter_ignored_ambiguities() {
            writeln!(message, "{}", components.get_name(*id).unwrap()).unwrap();
        }

        info!("{}", message);
    }
