Why a workflow call was refused.

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.

UnknownAction(String)

The action is not in the profile.

Invalid(&'static str)

A field failed validation.

Duplicate(String)

The request id exists.

NotFound(String)

TooManyOpen(usize)

AuditRequired

The action requires audit before effect and no sink is configured.

InvalidState

The call is not allowed from the request’s current state.

Fields

id: String

state: ApprovalState

NotApproved(String)

claim on a request that is still Pending.

AlreadyClaimed(String)

claim on a request that is already Claimed (or settled): the one claim is spent.

StaleClaim(String)

A token that is not the one on record.

Expired(String)

The request expired (and is now Expired).

StaleRevision

The decision named a revision other than the current one.

Fields

expected: u64

found: u64

Conflict(String)

Another caller changed the request first.

Unverified(String)

The verifier refused the proof.

ScopeDenied

The principal’s accounts do not cover the request’s account.

NotAnApprover

The request names approvers and the principal is not one.

ReplayedNonce

The proof’s nonce was already used.

NotRequester

Only the requester may cancel.

AuditFailed(String)

A required audit row could not be appended; see the operation for what that left.

Store(StoreError)

Trait Implementations

impl Debug for ApprovalError

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

Formats the value using the given formatter.

impl Display for ApprovalError

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

Formats the value using the given formatter.

impl Error for ApprovalError

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<StoreError> for ApprovalError

fn from(e: StoreError) -> Self

Converts to this type from the input type.
