pub struct TryRead<T>(_)
 where
    T: Component;

Reads a single entity data component type from a chunk, if it's present.

    T: Component, 

fn clone(&self) -> TryRead<T>

Returns a copy of the value.

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

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

Formats the value using the given formatter.

impl<T> Default for TryRead<T> where
    T: Component, 

fn default() -> TryRead<T>

impl<'a, T> DefaultFilter for TryRead<T> where
    T: Component, 

type Filter = EntityFilterTuple<Passthrough, Passthrough, Passthrough>

The type of entity filter constructed.

fn filter() -> <TryRead<T> as DefaultFilter>::Filter

constructs an entity filter.

impl<'a, T> View<'a> for TryRead<T> where
    T: Component, 

type Iter = TryRefIter<'a, T, Iter<'a, T>>

The iterator over the chunk data.

fn fetch(
    &'a ArchetypeData,
    chunk: &'a ComponentStorage,
    ChunkIndex,
    SetIndex
) -> <TryRead<T> as View<'a>>::Iter

Pulls data out of a chunk.

fn validate() -> bool

Validates that the view does not break any component borrowing rules.

fn reads<D>() -> bool where
    D: Component, 

Determines if the view reads the specified data type.

fn writes<D>() -> bool where
    D: Component, 

Determines if the view writes to the specified data type.

fn requires_permissions() -> Permissions<ComponentTypeId>

Returns the set of permissions required by the view.

fn validate_access(access: &ComponentAccess<'_>) -> bool

Determines if the given component access includes all permissions required by the view.
