Error code E0138
More than one function was declared with the #[start]
attribute.
Erroneous code example:
#![allow(unused)] #![feature(start)] fn main() { #[start] fn foo(argc: isize, argv: *const *const u8) -> isize {} #[start] fn f(argc: isize, argv: *const *const u8) -> isize {} // error: multiple 'start' functions }
This error indicates that the compiler found multiple functions with the
#[start]
attribute. This is an error because there must be a unique entry
point into a Rust program. Example:
#![allow(unused)] #![feature(start)] fn main() { #[start] fn foo(argc: isize, argv: *const *const u8) -> isize { 0 } // ok! }
