Every way the executor can refuse. All variants are refusal-first: nothing has been written when one of these is returned.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

ValidationFailed(String)

Re-validation against the current schema failed. Carries the human-readable reason so the caller can print it verbatim.

CriticalRiskNotAllowed

The document’s risk classifier reached Critical. Executing a plan at that level requires a reviewer to regenerate the plan under a changed posture — the executor will not do it.

DeveloperOnlyForbidden

The plan contains a developer-only primitive (e.g. CreateMigration). These must never flow through the AI path.

SchemaMismatch(String)

The plan was valid at save time but the current schema has drifted. The message names the step and the primitive error.

FileConflict

The executor was about to write a file that no longer matches the content recorded during the dry-run (or that exists when it shouldn’t). Never silently overwrite.

Fields

path: String

reason: String

UnsupportedPrimitive

The primitive is valid in principle but not wired up in 0.5.2.

Fields

op: &'static str

reason: &'static str

DestructiveWithoutConfirmation

A destructive primitive was requested without allow_destructive. Reserved for 0.5.3+; 0.5.2 refuses destructive ops regardless.

Fields

op: &'static str

ProjectStructure(String)

Expected project scaffolding isn’t present (apps/<x>/models.rs missing for a model, migrations/ directory missing, …).

IoError

Filesystem error during read or write. Carries the OS message plus the offending path.

Fields

path: String

message: String

PolicyViolation

The plan violates a policy derived from the project’s ContextConfig — for example, a remove_field targeting a field flagged as personally-identifying under GDPR, or a change_field_type on a regulated column. Refused up-front; the operator can edit the context file or the plan and re-run.

Fields

reason: String

Trait Implementations

impl Clone for ExecutionError

fn clone(&self) -> ExecutionError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ExecutionError

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

Formats the value using the given formatter.

impl Display for ExecutionError

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

Formats the value using the given formatter.

impl Error for ExecutionError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl PartialEq for ExecutionError

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