Enum LinkError 

pub enum LinkError {
    UnknownOntology {
        ontology: String,
    },
    MissingPeerArchive {
        ontology: String,
    },
    RootMismatch {
        ontology: String,
        pinned: ContentAddress,
        actual: ContentAddress,
    },
    AtomAbsent {
        ontology: String,
        atom: ContentAddress,
    },
    NotGrounded,
    Codec(CodecError),
}

Why a grounded edge could not be resolved — fail-closed, never a silent bind.

Variants

UnknownOntology

The edge grounds into an ontology the manifest does not declare (a resolve-time fault).

Fields

ontology: String

MissingPeerArchive

A manifest-DECLARED ontology has no supplied peer archive, so the resolver cannot be built (a build-time fault — distinct from UnknownOntology, which is an edge into an ontology the manifest never declared).

Fields

ontology: String

RootMismatch

A declared ontology was supplied, but its archive’s actual root disagrees with the pinned root — a version/content skew. Refused.

Fields

ontology: String

pinned: ContentAddress

actual: ContentAddress

AtomAbsent

The connected ontology holds no atom at the named address.

Fields

ontology: String

atom: ContentAddress

NotGrounded

The target is a Local edge — not a grounded edge to resolve. (Callers traverse local edges by name, not through here.)

Codec(CodecError)

A node or archive address could not be derived (codec failure).

Trait Implementations

impl Clone for LinkError

fn clone(&self) -> LinkError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LinkError

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

Formats the value using the given formatter.

impl Display for LinkError

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

Formats the value using the given formatter.

impl Eq for LinkError

impl Error for LinkError

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 LinkError

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