Variants

SameCurrencyIds

Error when order is placed attempting to exchange currencies of the same type.

BelowMinFulfillmentAmount

Error when an account cannot reserve or transfer the amount.

InvalidCurrencyId

Error when an order is placed with a currency that is not in the AssetRegistry.

OrderNotFound

Error when an operation is attempted on an order id that is not in storage.

Unauthorised

Error when a user attempts an action on an order they are not authorised to perform, such as cancelling another accounts order.

FulfillAmountTooLarge

Error when the provided amount to fulfill is too large for the order.

MarketFeederNotFound

There is not feeder set for market conversion ratios

MarketRatioNotFound

Expected a market ratio for the given pair of currencies.

Trait Implementations

impl<T: Config> Debug for Error<T>

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

Formats the value using the given formatter.

impl<T> Decode for Error<T>

fn decode<__CodecInputEdqy: Input>( __codec_input_edqy: &mut __CodecInputEdqy ) -> Result<Self, Error>

Attempt to deserialise the value from input.

fn decode_into<I>( input: &mut I, dst: &mut MaybeUninit<Self> ) -> Result<DecodeFinished, Error>

where I: Input,

Attempt to deserialize the value from input into a pre-allocated piece of memory.

fn skip<I>(input: &mut I) -> Result<(), Error>

where I: Input,

Attempt to skip the encoded value from input.

fn encoded_fixed_size() -> Option<usize>

Returns the fixed encoded size of the type.

impl<T> Encode for Error<T>

fn size_hint(&self) -> usize

If possible give a hint of expected size of the encoding.

fn encode_to<__CodecOutputEdqy: Output + ?Sized>( &self, __codec_dest_edqy: &mut __CodecOutputEdqy )

Convert self to a slice and append it to the destination.

fn encode(&self) -> Vec<u8>

Convert self to an owned vector.

fn using_encoded<R, F>(&self, f: F) -> R

where F: FnOnce(&[u8]) -> R,

Convert self to a slice and then invoke the given closure with it.

fn encoded_size(&self) -> usize

Calculates the encoded size.

impl<T: Config> From<Error<T>> for &'static str

fn from(err: Error<T>) -> &'static str

Converts to this type from the input type.

impl<T: Config> From<Error<T>> for DispatchError

fn from(err: Error<T>) -> Self

Converts to this type from the input type.

impl<T> PalletError for Error<T>

const MAX_ENCODED_SIZE: usize = 1usize

The maximum encoded size for the implementing type.

impl<T: PartialEq> PartialEq for Error<T>

fn eq(&self, other: &Error<T>) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<T> TypeInfo for Error<T>

where PhantomData<T>: TypeInfo + 'static, T: 'static,

type Identity = Error<T>

The type identifying for which type info is provided.

fn type_info() -> Type

Returns the static type identifier for Self.
