Fields

session: OnceCell<Session>

The current session.

uri: RefCell<Option<OwnedMxcUri>>

The Matrix URI of the avatar.

uri_string: PhantomData<Option<String>>

The Matrix URI of the AvatarImage, as a string.

info: RefCell<Option<ImageInfo>>

Information about the avatar.

uri_source: Cell<AvatarUriSource>

The source of the URI avatar.

scale_factor: Cell<u32>

The scale factor to use to load the cached paintable.

small_paintable_ref: OnceCell<CountedRef>

The counted reference for the small paintable.

The small paintable is cached indefinitely after the first reference is taken.

small_paintable: RefCell<Option<Paintable>>

The cached paintable of the avatar at small size, if any.

big_paintable_ref: OnceCell<CountedRef>

The counted reference for the big paintable.

The big paintable is cached after the first reference is taken and dropped when the last reference is dropped.

big_paintable: RefCell<Option<Paintable>>

The cached paintable of the avatar at big size, if any.

error: Cell<Option<ImageError>>

The last error encountered when loading the cached paintable of the avatar, if any.
