1#### Note: this error code is no longer emitted by the compiler.23More than one function was declared with the `#[main]` attribute.45Erroneous code example:67```compile_fail8#![feature(main)]910#[main]11fn foo() {}1213#[main]14fn f() {} // error: multiple functions with a `#[main]` attribute15```1617This error indicates that the compiler found multiple functions with the18`#[main]` attribute. This is an error because there must be a unique entry19point into a Rust program. Example:2021```compile_fail22#![feature(main)]2324#[main]25fn f() {} // ok!26```
