[][src]Trait std::process::Termination

#[lang = "termination"]
pub trait Termination { fn report(self) -> i32; }
🔬 This is a nightly-only experimental API. (termination_trait_lib #43301)

A trait for implementing arbitrary return types in the main function.

The c-main function only supports to return integers as return type. So, every type implementing the Termination trait has to be converted to an integer.

The default implementations are returning libc::EXIT_SUCCESS to indicate a successful execution. In case of a failure, libc::EXIT_FAILURE is returned.

Required methods

fn report(self) -> i32

🔬 This is a nightly-only experimental API. (termination_trait_lib #43301)

Is called to get the representation of the value as status code. This status code is returned to the operating system.
