Function paralegal_spdg::rustc::mir::create_dump_file

pub fn create_dump_file<'tcx>(
    tcx: TyCtxt<'tcx>,
    extension: &str,
    pass_num: bool,
    pass_name: &str,
    disambiguator: &dyn Display,

) -> Result<BufWriter<File>, Error>

Attempts to open a file where we should dump a given MIR or other bit of MIR-related data. Used by mir-dump, but also by other bits of code (e.g., NLL inference) that dump graphviz data or other things, and hence takes the extension as an argument.
