Enum FoldErrorPolicy 

pub enum FoldErrorPolicy {
    Stop,
    LogAndContinue,
}

What the fold task does when super::super::redex::RedexFold::apply returns an error.

Variants

Stop

First error stops the fold task. State remains readable as of the last successful apply. Subsequent ingests still succeed (the log is the source of truth; a broken fold is a bug in the fold, not in the data). A later process instance with a fixed fold can replay from the beginning and succeed. Default.

LogAndContinue

Log + skip. The offending event is not folded; the task continues with the next event. Visible via super::CortexAdapter::fold_errors. Useful for development; production CortEX should prefer Stop so bugs don’t silently corrupt derived state.

Trait Implementations

impl Clone for FoldErrorPolicy

fn clone(&self) -> FoldErrorPolicy

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FoldErrorPolicy

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

Formats the value using the given formatter.

impl PartialEq for FoldErrorPolicy

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