Enum Error

    LengthMismatch {
        declared: usize,
        actual: usize,
    },
    UnknownTag(u8),

}

A failure decoding a value, building/proving over the tree, or evaluating the pairing predicate.

Variants

TruncatedValue(&'static str)

A value blob was shorter than its declared header or length prefix.

LengthMismatch

A value’s declared length did not match the bytes that followed it.

Fields

declared: usize

The length written in the 4-byte big-endian prefix.

actual: usize

The number of payload bytes actually present.

UnknownTag(u8)

A value blob carried a tag byte this version does not define.

WrongWidth

A fixed-width value (u16/u32/u64) carried the wrong number of payload bytes.

Fields

tag: u8

The value tag whose width was violated.

expected: usize

The exact payload width the tag mandates.

actual: usize

The payload width actually present.

Smt(String)

The underlying sparse-merkle-tree rejected an update or proof operation.

NotAuthoritativeProfile

A composed profile-field verification was declined because the supplied store is NOT the DID’s authoritative profile (the DID↔store pairing predicate failed — see crate::pairing).

FieldProofRejected

A composed profile-field verification was declined because the merkle proof did not verify the claimed value (or absence) against the supplied profile root.

MintNotYetImplemented

IdentityProfile::mint_from_did is not yet implemented. Minting is GATED on the dig-store crate (#703/#754) and the WU3 chain layer (#778); dig-identity MUST NOT depend on dig-store (the dependency graph stays acyclic), so the launch driver lands as a WU2 follow-on — not here. The signature exists now so consumers code against the primitive’s final shape.

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Eq for Error

impl Error for Error

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<Error> for ResolveError

fn from(source: Error) -> Self

Converts to this type from the input type.

impl PartialEq for Error

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

Equality operator ==.

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

Inequality operator !=.
