Struct SumReducer 

pub struct SumReducer;

Reducer that adds values with AddAssign.

Trait Implementations

impl Clone for SumReducer

fn clone(&self) -> SumReducer

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SumReducer

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

Formats the value using the given formatter.

impl Default for SumReducer

fn default() -> SumReducer

Returns the “default value” for a type.

impl PartialEq for SumReducer

fn eq(&self, other: &SumReducer) -> 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<V> Reducer<V> for SumReducer

where V: AddAssign,

type Error = Infallible

Error returned when two values cannot be reduced.

fn reduce(&mut self, accumulator: &mut V, value: V) -> Result<(), Self::Error>

Adds value into accumulator.
