Enum PrimitiveError 

#[non_exhaustive]
pub enum PrimitiveError {
    EmptyIdentifier(&'static str),
    UnknownType {
        model: String,
        field: String,
        ty: String,
    },
    DuplicateFieldInAddModel {
        model: String,
        field: String,
    },
    AlreadyExists {
        what: &'static str,
        name: String,
    },
    NotFound {
        what: &'static str,
        name: String,
    },
    UnknownRelationTarget {
        from: String,
        to: String,
    },
    UnknownAdminAttribute {
        attr: String,
    },
    NoOpRename {
        what: &'static str,
        name: String,
    },
    DeveloperOnlyNotAllowedInPlan {
        op: &'static str,
    },
    InStep {
        step: usize,
        inner: Box<PrimitiveError>,
    },
}

Reasons a primitive (or a plan composed of primitives) can be rejected. The AI boundary converts these into a blunt refusal — the executor never silently “fixes” a primitive or applies a partial plan.

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.

EmptyIdentifier(&'static str)

A required identifier is empty (name, model, field, …).

UnknownType

A field’s declared type isn’t in VALID_TYPE_NAMES.

Fields

model: String

field: String

ty: String

DuplicateFieldInAddModel

Two fields with the same name inside an add_model payload.

Fields

model: String

field: String

AlreadyExists

Target of an add_* already exists in the schema.

Fields

what: &'static str

name: String

NotFound

Target of a remove_* / update_admin doesn’t exist.

Fields

what: &'static str

name: String

UnknownRelationTarget

Relation target model doesn’t exist in the (shadow-applied) schema.

Fields

from: String

to: String

UnknownAdminAttribute

UpdateAdmin referenced an attribute outside the accepted vocabulary.

Fields

attr: String

NoOpRename

A rename primitive was given identical from and to. Rejecting no-ops early keeps plans honest and diff-reviewable.

Fields

what: &'static str

name: String

DeveloperOnlyNotAllowedInPlan

A developer-only primitive appeared inside a Plan. Plans represent the AI boundary; anything with Primitive::is_developer_only set must be rejected before an executor touches it.

Fields

op: &'static str

InStep

validate_plan annotates inner errors with the step index so a caller can point the user at “step 3 failed because …”.

Fields

step: usize

inner: Box<PrimitiveError>

Trait Implementations

impl Clone for PrimitiveError

fn clone(&self) -> PrimitiveError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PrimitiveError

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

Formats the value using the given formatter.

impl Display for PrimitiveError

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

Formats the value using the given formatter.

impl Error for PrimitiveError

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 PrimitiveError

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