Enum AggregateOutputMode 

pub enum AggregateOutputMode {
    Partial,
    Final,
}

Whether an aggregate stage produces intermediate accumulator state or final output values.

See the table on AggregateMode for how this relates to aggregate modes.

Variants

Partial

The stage produces intermediate accumulator state, serialized via Accumulator::state.

Final

The stage produces final output values via Accumulator::evaluate.

Trait Implementations

impl Clone for AggregateOutputMode

fn clone(&self) -> AggregateOutputMode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AggregateOutputMode

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

Formats the value using the given formatter.

impl PartialEq for AggregateOutputMode

fn eq(&self, other: &AggregateOutputMode) -> 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.
