//! # Edit Message Example
//!
//! This example demonstrates how to edit a discord webhook message that originated from a
//! specific Webhook ID, Token, and Message ID. The arguments provided should be provided exactly
//! in that order.
//!
//! ## Example
//!
//! cargo run --example edit_message --features examples -- 00001111 aaaabbbb 22223333
//! where:
//!     Webhook ID: 00001111
//!     Token:      aaaabbbb
//!     Message ID: 22223333
