Struct wasm_react::hooks::Deps

pub struct Deps<T>(/* private fields */);

This struct specifies dependencies for certain hooks.

Example

use_effect(|| {
  log("This effect will be called every time `self.id` or `state.counter` changes.");

  || ()
}, Deps::some((self.id, state.counter)));

Implementations

impl Deps<()>

pub fn all() -> Self

The hook will be activated whenever the component renders.

pub fn none() -> Self

The hook will be activated only on the first render.

impl<T> Deps<T>

pub fn some(deps: T) -> Self

The hook will be activated every time when the component renders if the inner value T has changed from last render.

Trait Implementations

impl<T: Clone> Clone for Deps<T>

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

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T: Debug> Debug for Deps<T>

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

Formats the value using the given formatter.

impl<T: PartialEq> PartialEq<Deps<T>> for Deps<T>

fn eq(&self, other: &Deps<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.
