Enum ExitClass 

#[repr(i32)]
pub enum ExitClass {
    Generic = 1,
    Retryable = 2,
    DataIntegrity = 3,
    SchemaDrift = 4,
}

Machine-actionable exit-code taxonomy.

A scheduler keys its retry / alert policy off the numeric exit code:

code	class	scheduler action
0	success	— (handled separately, not in this enum)
1	Generic: config / usage / unclassified error	fix the config; do not retry blindly
2	Retryable: transient (connection reset, lock-wait timeout, capacity)	safe to retry the same command
3	DataIntegrity: quality gate / reconcile mismatch / validate verification failure / duplicate-guard / manifest inconsistency	STOP — data may be wrong, do not blindly retry
4	SchemaDrift: on_schema_drift: fail tripped	the source shape changed — needs human review

Overlap with clap’s usage exit (also 2)

clap exits 2 on an argument-parse error (bad flag, missing required arg). That collides numerically with Retryable = 2, but the two are distinguishable: clap’s exit happens pre-dispatch, before any rivet work runs, so it prints only a clap usage block and no Error: line. A retryable rivet failure always prints an Error: … line (or a JSON object with "exit_class": 2). We deliberately do not fight clap by remapping our retryable code — 2 = retryable matches the spec, and the usage overlap is documented and detectable by the absence of a rivet error line.

Variants

Generic = 1

1 — config / usage / unclassified error. Fix the input; retrying the identical command will fail the same way.

Retryable = 2

2 — transient failure (connection reset, lock-wait timeout, capacity). Safe to retry the same command after a backoff.

DataIntegrity = 3

3 — data-integrity failure (quality gate, reconcile mismatch, validate verification failure, duplicate-guard, manifest inconsistency). The exported data may be wrong; stop and investigate rather than retry.

SchemaDrift = 4

4 — schema-drift failure (on_schema_drift: fail tripped). The source shape changed; a human must review before re-running.

Implementations

impl ExitClass

pub fn code(self) -> i32

The process exit code for this class.

Trait Implementations

impl Clone for ExitClass

fn clone(&self) -> ExitClass

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for ExitClass

impl Debug for ExitClass

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

Formats the value using the given formatter.

impl Eq for ExitClass

impl PartialEq for ExitClass

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