Trait hecs_schedule::system::System

pub trait System<Args, Ret> {
    fn execute(&mut self, context: &Context<'_>) -> Result<()>;
    fn name(&self) -> SystemName;
    fn borrows() -> Borrows;

    fn named<S: Into<Cow<'static, str>>>(self, name: S) -> NamedSystem<Self>
    where
        Self: Sized,
    { ... }
}

Trait which defines any function or type that can operate on a world or other context.

Required methods

fn execute(&mut self, context: &Context<'_>) -> Result<()>

Executes the by borrowing from context

fn name(&self) -> SystemName

Returns the system name. Used for debug purposes

fn borrows() -> Borrows

Returns which data will be accessed

Provided methods

fn named<S: Into<Cow<'static, str>>>(self, name: S) -> NamedSystem<Self> where
    Self: Sized, 

Wrap the system with a custom name
