Enum AppExit 

pub enum AppExit {
    Ok,
    Error(String),
    RequestedByUser,
    Programmatic(String),
}

Application exit status.

Returned by App::run when the event loop terminates normally.

The RequestedByUser variant covers the common case of the user explicitly closing the window. Programmatic(reason) is used when code calls a controlled shutdown with an explanatory string. Ok is returned by the headless path and by backends that do not distinguish how the loop ended.

Variants

Ok

The application exited normally (user closed the window or event loop drained).

Error(String)

The application exited due to an error.

RequestedByUser

The user explicitly requested exit (e.g. clicked the close button).

Programmatic(String)

Programmatic shutdown with an explanatory reason string.

Trait Implementations

impl Clone for AppExit

fn clone(&self) -> AppExit

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for AppExit

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for AppExit

impl PartialEq for AppExit

fn eq(&self, other: &AppExit) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
