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: git_config_disclosure.rs
    path of file: ./repos/phaser/phaser/src/modules/http
    
    the code of the file until where you have to start completion: use crate::{
    modules::{HttpModule, Module, ModuleName, ModuleVersion},
    report::{Finding, ModuleResult, Severity},
    Error,
};
use async_trait::async_trait;
use regex::Regex;
use reqwest::Client;

pub struct GitConfigDisclosure {
    git_config_regex: Regex,
}

impl GitConfigDisclosure {
    pub fn new() -> Self {
        GitConfigDisclosure {
            git_config_regex: Regex::new(r#"\[branch "[^"]*"\]"#)
                .expect("compiling http/git_config_disclosure regexp"),
        }
    }

    async fn is_git_config_file(&self, content: String) -> Result<bool, Error> {
 
    
    async fn scan(&self, http_client: &Client, endpoint: &str) -> Result<Option<Finding>, Error> {
        let url = format!("{}/.git/config", &endpoint);
        let res = http_client.get(&url).send().await?;

        if !res.status().is_success() {
            return Ok(None);
        }

        let body = res.text().await?;
        if self.is_git_config_file(body).await? {
            return Ok(Some(Finding {
                module: self.name(),
                module_version: self.version(),
                severity: self.severity(),
                result: ModuleResult::Url(url),
            }));
        }

        Ok(None)
    }
