Why the common Allowance rules did not admit a candidate payment.

Variants

InvalidRequest

The caller supplied structurally invalid Payment Request terms.

AssetMismatch

Request and Allowance assets differ, including case.

AmountOutsideRange

Request amount is outside the inclusive per-payment range.

NoEligibleEndpoint

The request and Allowance have no common endpoint identifier.

NotActive

The inclusive active time has not been reached.

Expired

The exclusive expiry has been reached.

ClockRollback

Evaluation would move trusted time behind its durable watermark.

FutureUsage

Retained usage was admitted later than this evaluation time.

UsageAssetMismatch

Accounting evidence uses a different asset from the Allowance.

PeriodAmountLimit

One configured period amount ceiling would be exceeded.

Fields

index: usize

Index into the original period_limits array.

PeriodCountLimit

One configured period count ceiling would be exceeded.

Fields

index: usize

Index into the original period_limits array.

LifetimeAmountLimit

The lifetime amount ceiling would be exceeded.

ArithmeticOverflow

A time boundary, duration, or count cannot be represented safely.

Implementations

impl AllowanceEvaluationBlock

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

Stable machine-readable code without private values.

Trait Implementations

impl Clone for AllowanceEvaluationBlock

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AllowanceEvaluationBlock

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

Formats the value using the given formatter.

impl Display for AllowanceEvaluationBlock

impl Eq for AllowanceEvaluationBlock

impl Error for AllowanceEvaluationBlock

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 AllowanceEvaluationBlock

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

Equality operator ==.

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

Inequality operator !=.
