Struct SDL_AppResult 

#[repr(transparent)]
pub struct SDL_AppResult(pub c_uint);

Return values for optional main callbacks.

Returning SDL_APP_SUCCESS or SDL_APP_FAILURE from SDL_AppInit, SDL_AppEvent, or SDL_AppIterate will terminate the program and report success/failure to the operating system. What that means is platform-dependent. On Unix, for example, on success, the process error code will be zero, and on failure it will be 1. This interface doesn’t allow you to return specific exit codes, just whether there was an error generally or not.

Returning SDL_APP_CONTINUE from these functions will let the app continue to run.

See Main callbacks in SDL3 for complete details.

Available Since: This enum is available since SDL 3.2.0.

Implementations

impl SDL_AppResult

pub const SDL_APP_CONTINUE: SDL_AppResult

< Value that requests that the app continue from the main callbacks.

pub const SDL_APP_SUCCESS: SDL_AppResult

< Value that requests termination with success from the main callbacks.

pub const SDL_APP_FAILURE: SDL_AppResult

< Value that requests termination with error from the main callbacks.

Trait Implementations

impl Clone for SDL_AppResult

fn clone(&self) -> SDL_AppResult

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SDL_AppResult

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

Formats the value using the given formatter.

impl Hash for SDL_AppResult

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for SDL_AppResult

fn eq(&self, other: &SDL_AppResult) -> 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.
