Struct gpui2::Model

pub struct Model<T> { /* private fields */ }

Implementations

impl<T: 'static> Model<T>

pub fn downgrade(&self) -> WeakModel<T>

Downgrade the this to a weak model reference

pub fn into_any(self) -> AnyModel

Convert this into a dynamically typed model.

pub fn read<'a>(&self, cx: &'a AppContext) -> &'a T

pub fn read_with<'a, R, C: Context>( &self, cx: &'a C, f: impl FnOnce(&T, &AppContext) -> R ) -> C::Result<R>

pub fn update<C, R>( &self, cx: &mut C, update: impl FnOnce(&mut T, &mut ModelContext<'_, T>) -> R ) -> C::Result<R>where C: Context,

Update the entity referenced by this model with the given function.

The update function receives a context appropriate for its environment. When updating in an AppContext, it receives a ModelContext. When updating an a WindowContext, it receives a ViewContext.

Trait Implementations

impl<T> Clone for Model<T>

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T> Debug for Model<T>

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

Formats the value using the given formatter.

impl<T> Deref for Model<T>

type Target = AnyModel

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl<T> DerefMut for Model<T>

fn deref_mut(&mut self) -> &mut Self::Target

Mutably dereferences the value.

impl<T: 'static> Entity<T> for Model<T>

type Weak = WeakModel<T>

fn entity_id(&self) -> EntityId

fn downgrade(&self) -> Self::Weak

fn upgrade_from(weak: &Self::Weak) -> Option<Self>where Self: Sized,

impl<T> From<Model<T>> for AnyModel

fn from(model: Model<T>) -> Self

Converts to this type from the input type.

impl<T> Hash for Model<T>

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

Feeds this value into the given Hasher.

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<T> PartialEq<Model<T>> for Model<T>

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl<T> PartialEq<Model<T>> for WeakModel<T>

fn eq(&self, other: &Model<T>) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

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

impl<T> PartialEq<WeakModel<T>> for Model<T>

fn eq(&self, other: &WeakModel<T>) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

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