Trait apecs::CanFetch

pub trait CanFetch: Send + Sync + Sized {
    fn borrows() -> Vec<Borrow>;
    fn construct(loan_mngr: &mut LoanManager<'_>) -> Result<Self>;

    fn plugin() -> Plugin { ... }
}

Types that can be fetched from the World.

Required Methods

fn borrows() -> Vec<Borrow>

fn construct(loan_mngr: &mut LoanManager<'_>) -> Result<Self>

Attempt to construct Self with the given LoanManager.

Provided Methods

fn plugin() -> Plugin

Return a plugin containing the systems and sub-resources required to create and use the type.

This will be used by functions like World::with_plugin to ensure that a type’s resources have been created, and that the systems required for upkeep are included.
