Trait EntityCommandOutput 

pub trait EntityCommandOutput {
    type Out;
    type Error: Into<BevyError> + From<EntityMutableFetchError>;

    // Required method
    fn into_result(self) -> Result<Self::Out, Self::Error>;
}

A trait implemented for types that can be used as the output of an EntityCommand.

Required Associated Types

type Out

The type returned when the command is successfully applied.

type Error: Into<BevyError> + From<EntityMutableFetchError>

The error type returned when the command fails to apply. The type must be convertible into a BevyError and constructible from an EntityMutableFetchError.

Required Methods

fn into_result(self) -> Result<Self::Out, Self::Error>

Converts the output into a Result containing either the successful output or an error.
