Struct FoldOutcome 

pub struct FoldOutcome<S> {
    pub state: S,
    pub entries_processed: usize,
}

Outcome of a fold operation.

Deterministic: contains only derived state and entry count. No wall-clock timing.

Fields

state: S

The derived state.

entries_processed: usize

Number of entries processed.

Implementations

impl<S> FoldOutcome<S>

pub fn new(state: S, entries_processed: usize) -> Self

Create a new fold outcome.

pub fn map<T, F: FnOnce(S) -> T>(self, f: F) -> FoldOutcome<T>

Map the state to a different type.

Trait Implementations

impl<S: Clone> Clone for FoldOutcome<S>

fn clone(&self) -> FoldOutcome<S>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<S: Debug> Debug for FoldOutcome<S>

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

Formats the value using the given formatter.

impl<S: Default> Default for FoldOutcome<S>

fn default() -> Self

Returns the “default value” for a type.

impl<S: PartialEq> PartialEq for FoldOutcome<S>

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