Enum valence::prelude::AppExit

pub enum AppExit {
    Success,
    Error(NonZero<u8>),
}

Expand description

An event that indicates the App should exit. If one or more of these are present at the end of an update, the runner will end and (maybe) return control to the caller.

This event can be used to detect when an exit is requested. Make sure that systems listening for this event run before the current update ends.

§Portability

This type is roughly meant to map to a standard definition of a process exit code (0 means success, not 0 means error). Due to portability concerns (see ExitCode and process::exit) we only allow error codes between 1 and 255.

Variants§

Success

App exited without any problems.

Error(NonZero<u8>)

The App experienced an unhandleable error. Holds the exit code we expect our app to return.

Implementations§

impl AppExit

pub const fn error() -> AppExit

Creates a AppExit::Error with a error code of 1.

pub const fn is_success(&self) -> bool

Returns true if self is a AppExit::Success.

pub const fn is_error(&self) -> bool

Returns true if self is a AppExit::Error.

pub const fn from_code(code: u8) -> AppExit

Creates a AppExit from a code.

When code is 0 a AppExit::Success is constructed otherwise a AppExit::Error is constructed.
