Struct View

pub struct View<R>(/* private fields */);

A view into a node’s data, allowing limited mutation

Implementations

impl<R> View<R>

where R: Deref,

pub fn new(r: R) -> View<R>

Create a new value view

impl<'a, T> View<RwLockWriteGuard<'a, T>>

pub fn downgrade(self) -> View<RwLockReadGuard<'a, T>>

Downgrade this write view to a read view

pub fn downgrade_to_upgradeable(self) -> View<RwLockUpgradableReadGuard<'a, T>>

Downgrade this write view to an upgradeable read view

impl<'a, T> View<RwLockUpgradableReadGuard<'a, T>>

pub fn upgrade(self) -> View<RwLockWriteGuard<'a, T>>

Upgrade this read guard

pub fn try_upgrade(self) -> Result<View<RwLockWriteGuard<'a, T>>, Self>

Try to upgrade this read guard

impl<R> View<R>

where R: DerefMut<Target = ValueData>,

pub fn add_dependent(&mut self, dependent: WeakId)

Add a dependent to the given value

pub fn set_name(&mut self, name: String) -> Result<(), String>

Try to set the name of a given value

Trait Implementations

impl<R: Debug> Debug for View<R>

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

Formats the value using the given formatter.

impl<R, T> DerefMut for View<R>

where R: DerefMut<Target = Data<T>>,

fn deref_mut(&mut self) -> &mut Data<T>

Mutably dereferences the value.

impl<R: PartialEq> PartialEq for View<R>

fn eq(&self, other: &View<R>) -> bool

Tests for self and other values to be equal, and is used by ==.

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

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

impl<R> Deref for View<R>

where R: Deref,

type Target = <R as Deref>::Target

The resulting type after dereferencing.

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

Dereferences the value.
