Why a mandate’s grant chain could not be resolved into a trustworthy order.

Variants

InconsistentId

A grant’s declared id does not match its content.

Fields

grant_id: String

LeafMissing

mandate.grant_id names a grant that is not in the carried chain.

Fields

grant_id: String

AncestorMissing

A parent_grant_id points at a grant that is not present.

Fields

parent_grant_id: String

Cycle

Following parent links revisited a grant: the links form a cycle.

Fields

grant_id: String

UnreachableExtras

The carrier supplied grants that the walk never reached. Extra grants are refused rather than ignored – silently dropping them would let a carrier stuff a chain with decoys.

Fields

count: usize

Unsigned

A grant carried no signature, so its content is unattested.

Fields

grant_id: String

BadSignature

A grant’s signature does not verify against its grantor.

Fields

grant_id: String

Trait Implementations

impl Clone for ChainResolveError

fn clone(&self) -> ChainResolveError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ChainResolveError

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

Formats the value using the given formatter.

impl Display for ChainResolveError

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

Operator-facing wording. The CLI prints these verbatim, so each names the grant it is talking about: “unresolvable” without a subject leaves a reader nothing to go and look at.

impl Eq for ChainResolveError

impl Error for ChainResolveError

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 ChainResolveError

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

Equality operator ==.

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

Inequality operator !=.
