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: json.rs
    path of file: ./repos/doku/doku/src/printers
    
    the code of the file until where you have to start completion: mod ctxt;
mod formatting;
mod output;
mod print_array;
mod print_comment;
mod print_enum;
mod print_fields;
mod print_map;
mod print_optional;
mod print_scalar;
mod print_struct;
mod print_tuple;

use self::{ctxt::*, output::*};

        let fmt = self
            .formatting
            .map(Cow::Borrowed)
            .unwrap_or_else(|| Cow::Owned(Default::default()));

        let mut out = Output::new(fmt.as_ref());

        Ctxt {
            ty,
            val: self.value,
            vis: self.visibility,
