Enum AnchorValidationError 

pub enum AnchorValidationError {
    UnknownClass {
        got: Option<String>,
        allowed: &'static [&'static str],
    },
    UnknownGrain {
        got: Option<String>,
        allowed: &'static [&'static str],
    },
    UnknownHashStability {
        got: String,
        allowed: &'static [&'static str],
    },
    MissingArtifact,
    HashOnNonHashClass {
        class: &'static str,
    },
    GrainNamespaceUnsupported {
        grain: &'static str,
        medium_type: String,
        anchor_namespace: &'static str,
    },
}

A typed INVALID_ANCHOR refusal. The whole mutation refuses and the entity is not written; Self::detail carries the recovery payload (offending value + allowed set) the agent fixes from.

Variants

UnknownClass

Provenance class is absent or not one of the allowed wire strings.

Fields

got: Option<String>

allowed: &'static [&'static str]

UnknownGrain

Grain is absent or not one of the allowed wire strings.

Fields

got: Option<String>

allowed: &'static [&'static str]

UnknownHashStability

Hash stability, when supplied, is not an allowed wire string.

Fields

got: String

allowed: &'static [&'static str]

MissingArtifact

The artifact reference is missing or empty.

HashOnNonHashClass

A content hash was supplied on a class that carries no hash semantics (authored / informed-by).

Fields

class: &'static str

GrainNamespaceUnsupported

The grain cannot be expressed in the medium’s anchor namespace (per the E2 capability matrix), e.g. span on a non-path medium.

Fields

grain: &'static str

medium_type: String

anchor_namespace: &'static str

Implementations

impl AnchorValidationError

pub fn code(&self) -> &'static str

The stable typed code — always INVALID_ANCHOR_CODE.

pub fn detail(&self) -> BTreeMap<String, Value>

Structured recovery detail for the typed envelope: the offending field, its bad value, and the allowed set where one applies.

Trait Implementations

impl Clone for AnchorValidationError

fn clone(&self) -> AnchorValidationError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AnchorValidationError

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

Formats the value using the given formatter.

impl Display for AnchorValidationError

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

Formats the value using the given formatter.

impl Eq for AnchorValidationError

impl Error for AnchorValidationError

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 From<AnchorValidationError> for EngineError

fn from(source: AnchorValidationError) -> Self

Converts to this type from the input type.

impl PartialEq for AnchorValidationError

fn eq(&self, other: &AnchorValidationError) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
