Type Alias Result

pub type Result<T = (), E = BevyError> = Result<T, E>;

A result type for use in fallible systems, commands and observers.

The BevyError type is a type-erased error type with optional Bevy-specific diagnostics.

Aliased Type

enum Result<T = (), E = BevyError> {
    Ok(T),
    Err(E),
}

Variants

Ok(T)

Contains the success value

Err(E)

Contains the error value

Trait Implementations

impl IntoScheduleConfigs<Box<dyn System<Out = Result<(), BevyError>, In = ()>>, ()> for BoxedSystem<(), Result>

fn into_configs(self) -> ScheduleConfigs<ScheduleSystem>

Convert into a ScheduleConfigs.

fn in_set(self, set: impl SystemSet) -> ScheduleConfigs<T>

Add these systems to the provided set.

fn before<M>(self, set: impl IntoSystemSet<M>) -> ScheduleConfigs<T>

Runs before all systems in set. If self has any systems that produce Commands or other Deferred operations, all systems in set will see their effect.

fn after<M>(self, set: impl IntoSystemSet<M>) -> ScheduleConfigs<T>

Run after all systems in set. If set has any systems that produce Commands or other Deferred operations, all systems in self will see their effect.

fn before_ignore_deferred<M>( self, set: impl IntoSystemSet<M>, ) -> ScheduleConfigs<T>

Run before all systems in set.

fn after_ignore_deferred<M>( self, set: impl IntoSystemSet<M>, ) -> ScheduleConfigs<T>

Run after all systems in set.

fn distributive_run_if<M>( self, condition: impl Condition<M> + Clone, ) -> ScheduleConfigs<T>

Add a run condition to each contained system.

fn run_if<M>(self, condition: impl Condition<M>) -> ScheduleConfigs<T>

Run the systems only if the Condition is true.

fn ambiguous_with<M>(self, set: impl IntoSystemSet<M>) -> ScheduleConfigs<T>

Suppress warnings and errors that would result from these systems having ambiguities (conflicting access but indeterminate order) with systems in set.

fn ambiguous_with_all(self) -> ScheduleConfigs<T>

Suppress warnings and errors that would result from these systems having ambiguities (conflicting access but indeterminate order) with any other system.

fn chain(self) -> ScheduleConfigs<T>

Treat this collection as a sequence of systems.

fn chain_ignore_deferred(self) -> ScheduleConfigs<T>

Treat this collection as a sequence of systems.
