Enum ErrorPolicy 

pub enum ErrorPolicy {
    FailFast,
    Continue,
    DeadLetter,
}

Per-stage policy for how errors propagate.

Variants

FailFast

The first stage error cancels the entire pipeline and bubbles out of crate::Pipeline::run. Default.

Continue

Stage errors are dropped along with the failing item; downstream continues to receive subsequent items.

DeadLetter

Stage errors are routed as StageFailure records to a dead-letter sink installed via crate::PipelineBuilder::dead_letter. If no dead-letter sink is installed the failing record is silently dropped (same as ErrorPolicy::Continue).

Trait Implementations

impl Clone for ErrorPolicy

fn clone(&self) -> ErrorPolicy

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ErrorPolicy

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

Formats the value using the given formatter.

impl Default for ErrorPolicy

fn default() -> ErrorPolicy

Returns the “default value” for a type.

impl Hash for ErrorPolicy

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for ErrorPolicy

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