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: sources.rs
    path of file: ./repos/cargo-deny/src
    
    the code of the file until where you have to start completion: pub mod cfg;
mod diags;
use cfg::ValidConfig;
pub use diags::Code;

use crate::{
    diag::{CfgCoord, Check, ErrorSink, Label, Pack},
    LintLevel,
};

const CRATES_IO_URL: &str = "https://github.com/rust-lang/crates.io-index";

pub fn check(ctx: crate
    
fn get_org(url: &url::Url) -> Option<(OrgType, &str)> {
    url.domain().and_then(|domain| {
        let org_type = if domain.eq_ignore_ascii_case("github.com") {
            OrgType::Github
        } else if domain.eq_ignore_ascii_case("gitlab.com") {
            OrgType::Gitlab
        } else if domain.eq_ignore_ascii_case("bitbucket.org") {
            OrgType::Bitbucket
        } else {
            return None;
        };

        url.path_segments()
            .and_then(|mut f| f.next())
            .map(|org| (org_type, org))
    })
}
