Enum slint::PlatformError

#[non_exhaustive]
pub enum PlatformError {
    NoPlatform,
    NoEventLoopProvider,
    SetPlatformError(SetPlatformError),
    Other(String),
}
Expand description

The platform encountered a fatal error.

This error typically indicates an issue with initialization or connecting to the windowing system.

This can be constructed from a String:

use slint::platform::PlatformError;
PlatformError::from(format!("Could not load resource {}", 1234));

Variants (Non-exhaustive)§

This enum is marked as non-exhaustive
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
§

NoPlatform

No default platform was selected, or no platform could be initialized.

If you encounter this error, make sure to either selected trough the backend-* cargo features flags, or call platform::set_platform() before running the event loop

§

NoEventLoopProvider

The Slint Platform does not provide an event loop.

The Platform::run_event_loop is not implemented for the current platform.

§

SetPlatformError(SetPlatformError)

There is already a platform set from another thread.

§

Other(String)

Another platform-specific error occurred
