Struct MintQuoteCustomResponse 

pub struct MintQuoteCustomResponse<Q> {
    pub quote: Q,
    pub request: String,
    pub amount: Option<Amount>,
    pub unit: Option<CurrencyUnit>,
    pub state: QuoteState,
    pub expiry: Option<u64>,
    pub pubkey: Option<PublicKey>,
    pub extra: Value,
}

Custom payment method mint quote response

This is a generic response type for custom payment methods.

The extra field allows payment-method-specific fields to be included without being nested. When serialized, extra fields merge into the parent JSON:

{
  "quote": "abc123",
  "state": "UNPAID",
  "amount": 1000,
  "paypal_link": "https://paypal.me/merchant",
  "paypal_email": "merchant@example.com"
}

This separation enables proper validation layering: the mint verifies well-defined fields (amount, unit, state, etc.) while passing extra through to the gRPC payment processor for method-specific validation.

It also provides a clean upgrade path: when a payment method becomes speced, its fields can be promoted from extra to well-defined struct fields without breaking existing clients (e.g., bolt12’s amount_paid and amount_issued).

Fields

quote: Q

Quote ID

request: String

Payment request string (method-specific format)

amount: Option<Amount>

Amount

unit: Option<CurrencyUnit>

Currency unit

state: QuoteState

Quote State

expiry: Option<u64>

Unix timestamp until the quote is valid

pubkey: Option<PublicKey>

NUT-19 Pubkey

extra: Value

Extra payment-method-specific fields

These fields are flattened into the JSON representation, allowing custom payment methods to include additional data without nesting.

Implementations

impl<Q> MintQuoteCustomResponse<Q>

where Q: ToString,

pub fn to_string_id(&self) -> MintQuoteCustomResponse<String>

Convert the MintQuoteCustomResponse with a quote type Q to a String

Trait Implementations

impl<Q> Clone for MintQuoteCustomResponse<Q>

where Q: Clone,

fn clone(&self) -> MintQuoteCustomResponse<Q>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl From<MintQuoteCustomResponse<QuoteId>> for MintQuoteCustomResponse<String>

Available on crate feature mint only.

fn from( value: MintQuoteCustomResponse<QuoteId>, ) -> MintQuoteCustomResponse<String>

Converts to this type from the input type.

impl<Q> PartialEq for MintQuoteCustomResponse<Q>
