Struct ReducerResult 

pub struct ReducerResult<E> {
    pub changed: bool,
    pub effects: Vec<E>,
}

Result of dispatching an action to an effect-aware store.

Contains both the state change indicator and any effects to be processed.

Fields

changed: bool

Whether the state was modified by this action.

effects: Vec<E>

Effects to be processed after dispatch.

Implementations

impl<E> ReducerResult<E>

pub fn unchanged() -> ReducerResult<E>

Create a result indicating no state change and no effects.

pub fn changed() -> ReducerResult<E>

Create a result indicating state changed but no effects.

pub fn effect(effect: E) -> ReducerResult<E>

Create a result with a single effect but no state change.

pub fn effects(effects: Vec<E>) -> ReducerResult<E>

Create a result with multiple effects but no state change.

pub fn changed_with(effect: E) -> ReducerResult<E>

Create a result indicating state changed with a single effect.

pub fn changed_with_many(effects: Vec<E>) -> ReducerResult<E>

Create a result indicating state changed with multiple effects.

pub fn with(self, effect: E) -> ReducerResult<E>

Add an effect to this result.

pub fn mark_changed(self) -> ReducerResult<E>

Set the changed flag to true.

pub fn has_effects(&self) -> bool

Returns true if there are any effects to process.

Trait Implementations

impl<E> Clone for ReducerResult<E>

where E: Clone,

fn clone(&self) -> ReducerResult<E>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<E> Debug for ReducerResult<E>

where E: Debug,

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

Formats the value using the given formatter.

impl<E> Default for ReducerResult<E>

fn default() -> ReducerResult<E>

Returns the “default value” for a type.

impl<E> PartialEq for ReducerResult<E>

where E: PartialEq,

fn eq(&self, other: &ReducerResult<E>) -> 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.
