impl AvatarImage

pub(crate) const SMALL_PAINTABLE_SIZE: u32 = 48

The small size of the paintable.

This is usually the size presented in the timeline or the sidebar. This is also the size of the avatar in GNOME Shell notifications.

This matches an avatar of size 48 or smaller. This size is cached indefinitely after the first AvatarImage::small_paintable_ref() is taken.

pub(crate) const BIG_PAINTABLE_SIZE: u32 = 150

The big size of the paintable.

This is usually the size presented in the room details or user profile.

This matches an avatar of size 150 or smaller. This is only cached when at least one AvatarImage::big_paintable_ref() is held.

pub(crate) fn new( session: &Session, uri_source: AvatarUriSource, uri: Option<OwnedMxcUri>, info: Option<ImageInfo>, ) -> Self

Construct a new AvatarImage with the given session, Matrix URI and avatar info.

pub(crate) fn set_uri_and_info( &self, uri: Option<OwnedMxcUri>, info: Option<ImageInfo>, )

Set the Matrix URI and information of the avatar.

pub(crate) fn uri(&self) -> Option<OwnedMxcUri>

The Matrix URI of the avatar.

pub(crate) fn small_paintable_ref(&self) -> CountedRef

Get a small paintable ref.

pub(crate) fn big_paintable_ref(&self) -> CountedRef

Get a big paintable ref.

pub(crate) async fn load_small_paintable( &self, ) -> Result<Option<Paintable>, ImageError>

Get the small paintable.

We first try to get it from the cache, and load it if it is not cached.

pub(crate) fn error(&self) -> Option<ImageError>

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

pub fn connect_error_changed<F: Fn(&Self) + 'static>( &self, f: F, ) -> SignalHandlerId

Connect to the signal emitted when the error changed.

Trait Implementations

impl Clone for AvatarImage

fn clone(&self) -> Self

Makes a clone of this shared reference.

This increments the strong reference count of the object. Dropping the object will decrement it again.

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

Performs copy-assignment from source.

impl Debug for AvatarImage

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

Formats the value using the given formatter.

impl HasParamSpec for AvatarImage

type ParamSpec = ParamSpecObject

type SetValue = AvatarImage

Preferred value to be used as setter for the associated ParamSpec.

type BuilderFn = fn(&str) -> ParamSpecObjectBuilder<'_, AvatarImage>

fn param_spec_builder() -> Self::BuilderFn

impl Hash for AvatarImage

fn hash<H>(&self, state: &mut H)

where H: Hasher,

Hashes the memory address of this object.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl ObjectSubclassIs for AvatarImage

type Subclass = AvatarImage

impl Ord for AvatarImage

fn cmp(&self, other: &Self) -> Ordering

Comparison for two GObjects.

Compares the memory addresses of the provided objects.

fn max(self, other: Self) -> Self

where Self: Sized,

impl<OT: ObjectType> PartialEq<OT> for AvatarImage

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

Equality for two GObjects.

Two GObjects are equal if their memory addresses are equal.

Partial comparison for two GObjects.

Compares the memory addresses of the provided objects.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
