Enum PlatformError 

pub enum PlatformError {
    EventLoop(EventLoopError),
    Window(OsError),
    Surface(SoftBufferError),
    Renderer(String),
    ClearColor,
}

Something that stopped a window from opening, running or presenting a frame.

Variants

EventLoop(EventLoopError)

The event loop could not be created or run to completion.

Window(OsError)

The operating system refused to create the window.

Surface(SoftBufferError)

The software presentation surface could not be created, resized or presented.

Renderer(String)

The renderer could not be set up for the window.

This holds what went wrong: a value of the SMUDGE_RENDERER environment variable that is not cpu, gpu or auto, a request for the GPU renderer without the gpu feature, a request for the GPU renderer with no usable adapter, or a window the GPU renderer cannot present to.

ClearColor

The window options gave a clear color that is not opaque.

Presentation copies only the color channels of the surface into the window, so a clear color with any transparency cannot be shown.

Trait Implementations

impl Debug for PlatformError

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

Formats the value using the given formatter.

impl Display for PlatformError

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

Formats the value using the given formatter.

impl Error for PlatformError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.
