The Error enum of this pallet.

Variants

InvalidPooledCurrency

The currency id can’t join stable amm pool.

InvalidLpCurrency

The currency id can’t become the lp currency id of stable amm pool.

MismatchParameter

The parameters of a call are contradictory.

InvalidCurrencyDecimal

The decimal of currency is invalid when create pool.

InvalidPoolId

The pool id is invalid.

InvalidBasePool

The base pool mismatch this pool.

Arithmetic

The error generate by some arithmetic function.

Deadline

The call already expired.

InsufficientSupply

The caller does not have enough currencies.

InsufficientReserve

The pool does not have enough currencies.

CheckDFailed

The new d below then older.

AmountSlippage

Slippage is too large.

SwapSameCurrency

Forbid swap same currency.

CurrencyIndexOutRange

The index of currency id bigger the length of pool’s currencies.

InsufficientLpReserve

The pool does not have enough lp currency.

ExceedThreshold

The setting value exceed threshold.

RampADelay

The A of this pool is already ramped in current period.

MinRampTime

The value of feature_a_time is too small.

ExceedMaxAChange

Forbid change A of a pool bigger than MAX_A.

AlreadyStoppedRampA

The ramping A of this pool is already stopped.

ExceedMaxFee

The fee parameter exceeds MAX_SWAP_FEE when creating the pool.

ExceedMaxAdminFee

The admin fee parameter exceeds MAX_ADMIN_FEE when creating the pool.

ZeroA

The A parameter cannot be zero when creating the pool.

ExceedMaxA

The A parameter exceed MAX_A when creating the pool.

LpCurrencyAlreadyUsed

The lp currency id is already used when create pool.

RequireAllCurrencies

Require all currencies of this pool when first supply.

TooManyCurrencies

The number of currencies exceeds the length limit.

BadPoolCurrencySymbol

The symbol of created pool exceeds the length limit.

InvalidTransaction

The transaction change nothing.

InvalidBasePoolLpCurrency

The base pool lp currency is invalid when create meta pool.

TokenIndexOutOfRange

The token index out of range.
