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: language.rs
    path of file: ./repos/probe-rs/probe-rs/src/debug
    
    the code of the file until where you have to start completion: use gimli::DwLang;

use crate::{
    debug::{
        Bitfield, DebugError, Modifier, Variable, VariableCache, VariableName, VariableType,
        VariableValue,
    },
    MemoryInterface,
};

/// C, C89, C99, C11, ...
pub mod c;
/// Rust
pub mod rust;

mod parsing;
mod value;

pub fn from_dwarf(dwarf_language: DwLang) -> Box<dyn ProgrammingLanguage> {
    match dwarf_language {
  
    
pub fn from_dwarf(dwarf_language: DwLang) -> Box<dyn ProgrammingLanguage> {
    match dwarf_language {
        // Handle all C-like languages the same now.
        // We may have to split it later if this is not good enough.
        gimli::DW_LANG_C
        | gimli::DW_LANG_C89
        | gimli::DW_LANG_C99
