Struct AllowanceEvaluationInput 

pub struct AllowanceEvaluationInput<'a> {
    pub terms: &'a AllowanceTerms,
    pub request: &'a PaymentRequestTerms,
    pub trusted_time: DateTime<Utc>,
    pub watermark: DateTime<Utc>,
    pub usage: &'a [AllowanceUsageEntry],
}

Explicit inputs to common eligibility math, without lifecycle or payment authority.

usage must contain all committed and unresolved automatic usage for these exact Allowance Terms, once per semantic payment key. The SDK must establish complete, current accounting and watermark evidence before calling this API; an empty slice cannot prove that an Allowance has never been used.

Fields

terms: &'a AllowanceTerms

Immutable shared Allowance Terms.

request: &'a PaymentRequestTerms

Immutable Payment Request terms.

trusted_time: DateTime<Utc>

Wallet-supplied trusted UTC time.

watermark: DateTime<Utc>

Persisted nondecreasing evaluation-time watermark, never a guessed default.

usage: &'a [AllowanceUsageEntry]

Complete committed usage and unresolved reservations, excluding the candidate.
