How to disable unused code warnings in Rust?

There are many ways to disable unused code warnings in Rust:

Add an allow attribute on a struct, module, function, etc.:

#[allow(dead_code)]
struct StructExample;

Add a crate-level allow attribute; notice the !:

#![allow(dead_code)]

Pass it to rustc:

rustc -A dead_code main.rs

Pass it using cargo via the RUSTFLAGS environment variable:

RUSTFLAGS="$RUSTFLAGS -A dead_code" cargo build
