Trait HandleError

pub trait HandleError<Out = ()> {
    // Required method
    fn handle_error_with(
        self,
        error_handler: fn(_: BevyError, _: ErrorContext),
    ) -> impl Command;

    // Provided method
    fn handle_error(self) -> impl Command
       where Self: Sized { ... }
}

Takes a Command that returns a Result and uses a given error handler function to convert it into a Command that internally handles an error if it occurs and returns ().

Required Methods

fn handle_error_with( self, error_handler: fn(_: BevyError, _: ErrorContext), ) -> impl Command

Takes a Command that returns a Result and uses a given error handler function to convert it into a Command that internally handles an error if it occurs and returns ().

Provided Methods

fn handle_error(self) -> impl Command

where Self: Sized,

Takes a Command that returns a Result and uses the default error handler function to convert it into a Command that internally handles an error if it occurs and returns ().

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
