impl<T: Component> DefaultFilter for TryRead<T>
type Filter = EntityFilterTuple<TryComponentFilter<T>, Passthrough>
type Filter = EntityFilterTuple<TryComponentFilter<T>, Passthrough>
The filter constructed.
sourceimpl<'data, T: Component> View<'data> for TryRead<T>
impl<'data, T: Component> View<'data> for TryRead<T>
type Fetch = Slice<'data, T>
type Fetch = Slice<'data, T>
The fetch type yielded for each archetype.
type Iter = TryReadIter<'data, T>
type Iter = TryReadIter<'data, T>
The iterator type which pulls entity data out of a world.
type Read = [ComponentTypeId; 1]
type Read = [ComponentTypeId; 1]
Contains the type IDs read by the view.
type Write = [ComponentTypeId; 0]
type Write = [ComponentTypeId; 0]
Contains the type IDs written by the view.
sourcefn validate_access(access: &ComponentAccess<'_>) -> bool
fn validate_access(access: &ComponentAccess<'_>) -> bool
Returns true if the given component access includes all permissions required by the view.
sourcefn reads_types() -> Self::Read
fn reads_types() -> Self::Read
Returns the component types read by the view.
sourcefn writes_types() -> Self::Write
fn writes_types() -> Self::Write
Returns the component types written to by the view.
sourcefn requires_permissions() -> Permissions<ComponentTypeId>
fn requires_permissions() -> Permissions<ComponentTypeId>
Returns a permissions struct declaring the component accesses required by the view.
