ErrorCategory ​

cpp
enum class ErrorCategory

Stable categories for errors returned by the public API.

枚举值

  • invalid_option= 1 — An option type or combination is unsupported.
  • invalid_strike= 2 — A strike is non-finite or outside its valid range.
  • invalid_volatility= 3 — A volatility is non-finite or non-positive.
  • invalid_risk_free_rate= 4 — A risk-free rate is non-finite.
  • invalid_dividend_yield= 5 — A dividend yield is non-finite.
  • invalid_spot_price= 6 — A spot price is non-finite or non-positive.
  • invalid_date= 7 — A date is unsupported or invalid for the operation.
  • invalid_time_range= 8 — A time range is reversed or outside an instrument life.
  • invalid_result= 9 — A requested pricing result is unavailable or invalid.
  • invalid_schedule= 10 — Schedule dates or counts violate contract rules.
  • invalid_calendar= 11 — A trading-calendar definition is invalid.
  • invalid_parameter= 12 — Another numeric or enum parameter is invalid.
  • unbracketed_volatility= 13 — Volatility bounds do not bracket the observed price.
  • solver_non_convergence= 14 — A numerical solver exhausted its iterations.
  • solver_non_finite= 15 — A numerical solver encountered a non-finite value.
  • unbracketed_coupon= 16 — Coupon bounds do not bracket the observed price.
  • backend_unavailable= 17 — The requested pricing backend is not available.
  • backend_failure= 18 — The selected backend failed during pricing.
  • unsupported_operation= 19 — The operation is not supported for the supplied inputs.

Result ​

cpp
template <typename T>
using kiyosi::Result = std::expected<T, Error>

Result of a public operation, containing either T or an Error. Domain rejections and reported backend failures use Error; Result is not a no-throw guarantee. Allocation failures propagate std::bad_alloc, including CUDA device-memory exhaustion. Other runtime/internal exceptions, such as entropy-source failures when choosing a random seed, propagate unchanged. Valid settings do not guarantee that required resources exist. CUDA unavailability and execution failures use backend_unavailable and backend_failure; invalid numerical results use invalid_result. Operations are synchronous and provide no cancellation interface or cancellation Error category.

kiyosi::Error ​

cpp
struct kiyosi::Error

Describes a failed domain or operational result.

category ​

cpp
ErrorCategory kiyosi::Error::category

Stable machine-readable failure category.

message ​

cpp
std::string kiyosi::Error::message

Human-readable diagnostic; callers must not parse it.
