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: unicode.rs
    path of file: ./repos/pomsky/pomsky-syntax/src/exprs/char_class
    
    the code of the file until where you have to start completion: use super::char_group::GroupName;
use crate::error::CharClassError;

include!(concat!(env!("OUT_DIR"), "/unicode_data.rs"));

pub(super) fn parse_group_name(name: &str) -> Result<GroupName, CharClassError> {
    match PARSE_LUT.binary_sear
    
pub(super) fn parse_group_name(name: &str) -> Result<GroupName, CharClassError> {
    match PARSE_LUT.binary_search_by_key(&name, |(k, _)| k) {
        Ok(n) => Ok(PARSE_LUT[n].1),
        Err(_) => Err(CharClassError::UnknownNamedClass {
            found: name.into(),
            #[cfg(feature = "suggestions")]
            similar: crate::util::find_suggestion(name, PARSE_LUT.iter().map(|&(name, _)| name)),
        }),
    }
}
