Struct Reduce 

pub struct Reduce<S, A> { /* private fields */ }

Named inline reducer wrapping a fn pointer. Type-erased reducer wrapper for composition.

Implementations

impl<S, A> Reduce<S, A>

pub const fn new(reduce: fn(&mut S, A) -> Cmd<A>) -> Self

pub const fn none() -> Self

where S: Default,

Trait Implementations

impl<S: Clone, A: Clone> Clone for Reduce<S, A>

fn clone(&self) -> Reduce<S, A>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<S: Copy, A: Copy> Copy for Reduce<S, A>

impl<S: Debug, A: Debug> Debug for Reduce<S, A>

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

Formats the value using the given formatter.

impl<S: Eq, A: Eq> Eq for Reduce<S, A>

impl<S: PartialEq, A: PartialEq> PartialEq for Reduce<S, A>

fn eq(&self, other: &Reduce<S, A>) -> 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.
