Struct Nil 

pub struct Nil;

The terminal element of a cons-list.

Trait Implementations

impl AccessCount for Nil

fn writers(_type_id: TypeId) -> usize

Returns how many writers for the given type exist in this list.

fn readers(_type_id: TypeId) -> usize

Returns how many readers for the given type exist in this list (both exclusive and non-exclusive).

fn exclusive_readers(_type_id: TypeId) -> usize

Returns how many exclusive readers for the given type exist in this list.

impl ActorList<'_> for Nil

type StoreRequests = Nil

A cons-list-of-cons-list-of-store-requests for this cons-list (essentially self.map(|actor| actor.store_request) where each actor has a cons-list of store-requests).

type InitContexts = Nil

A cons-list of init-contexts for this cons-list (essentially self.map(|actor| actor.init_context)).

impl Clone for Nil

fn clone(&self) -> Nil

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Nil

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl IntoSlots for Nil

type Slots = Nil

A cons-list that contains a slot for every type in this cons-list.

fn make_slots() -> Self::Slots

Creates a new instance of the slot cons-list with all slots empty.

impl NestedAccessCount for Nil

fn writers(_type_id: TypeId) -> usize

Returns how many writers for the given type exist in this list of lists.

fn readers(_type_id: TypeId) -> usize

Returns how many readers for the given type exist in this list of lists (both exclusive and non-exclusive).

fn exclusive_readers(_type_id: TypeId) -> usize

Returns how many exclusive readers for the given type exist in this list of lists.

impl PartialEq for Nil

fn eq(&self, other: &Nil) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Slots for Nil

fn slot<T>(self: Pin<&Self>) -> Pin<&Slot<T>>

where T: Storable + 'static,

See Datastore::slot.

fn all_slots() -> impl Iterator<Item = (TypeId, &'static str)>

Returns the TypeId and type names for all the slots stored in this type.

impl Copy for Nil

impl Eq for Nil

impl StructuralPartialEq for Nil
