Trait EntityCapabilityProvider 

pub trait EntityCapabilityProvider<T, C>: Send + Sync
where
    T: ?Sized,
{
    // Required method
    fn provide(
        &self,
        host: &mut dyn ServerHost,
        entity: EntityRef,
        context: C,
    ) -> Option<Box<T>>;
}

What answers an entity capability for one entity type: given the entity and the lookup’s context (its EntityCapabilityKey’s C), its handler, or none to leave it to the next provider. A closure is one.

Required Methods

fn provide( &self, host: &mut dyn ServerHost, entity: EntityRef, context: C, ) -> Option<Box<T>>

The handler for entity, asked with context, or none.

Trait Implementations

impl Wire for Box<dyn EntityCapabilityProvider<dyn ResourceHandler<ItemResource>, ()>>

const MIN: usize = 8

Minimum encoded size, used to reject impossible collection lengths.

fn put(&self, out: &mut Writer)

Encodes this value, recording failures on the writer.

fn put_owned(self, out: &mut Writer)

Consumes owned data when a resource’s ownership must cross the boundary.

fn take( input: &mut Reader<'_>, ) -> Result<Box<dyn EntityCapabilityProvider<dyn ResourceHandler<ItemResource>, ()>>, WireError>

Decodes one value, leaving any following bytes for the caller.

impl Wire for Box<dyn EntityCapabilityProvider<dyn ResourceHandler<ItemResource>, Option<Direction>>>

const MIN: usize = 8

Minimum encoded size, used to reject impossible collection lengths.

fn put(&self, out: &mut Writer)

Encodes this value, recording failures on the writer.

fn put_owned(self, out: &mut Writer)

Consumes owned data when a resource’s ownership must cross the boundary.

Decodes one value, leaving any following bytes for the caller.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
