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: mod.rs
    path of file: ./repos/pixi/src/cli/project/channel
    
    the code of the file until where you have to start completion: pub mod add;
pub mod list;
pub mod remove;

use crate::Project;
use clap::Parser;
use std::path::PathBuf;

/// Commands to manage project channels.
#[derive(Parser, Debug)]
pub struct Args {
    /// The path to 'pixi.toml'
    #[c
    
pub async fn execute(args: Args) -> miette::Result<()> {
    let project = Project::load_or_else_discover(args.manifest_path.as_deref())?;

    match args.command {
        Command::Add(args) => add::execute(project, args).await,
        Command::List(args) => list::execute(project, args),
        Command::Remove(args) => remove::execute(project, args).await,
    }
}
