Errors that may be returned by the TokenSwap program.

Variants

AlreadyInUse

The account cannot be initialized because it is already being used.

InvalidProgramAddress

The program address provided doesn’t match the value generated by the program.

InvalidOwner

The owner of the input isn’t set to the program address generated by the program.

InvalidOutputOwner

The owner of the pool token output is set to the program address generated by the program.

ExpectedMint

The deserialization of the account returned something besides State::Mint.

ExpectedAccount

The deserialization of the account returned something besides State::Account.

EmptySupply

The input token account is empty.

InvalidSupply

The pool token mint has a non-zero supply.

InvalidDelegate

The provided token account has a delegate.

InvalidInput

The input token is invalid for swap.

IncorrectSwapAccount

Address of the provided swap token account is incorrect.

IncorrectPoolMint

Address of the provided pool token mint is incorrect

InvalidOutput

The output token is invalid for swap.

CalculationFailure

General calculation failure due to overflow or underflow

InvalidInstruction

Invalid instruction number passed in.

RepeatedMint

Swap input token accounts have the same mint

ExceededSlippage

Swap instruction exceeds desired slippage limit

InvalidCloseAuthority

The provided token account has a close authority.

InvalidFreezeAuthority

The pool token mint has a freeze authority.

IncorrectFeeAccount

The pool fee token account is incorrect

ZeroTradingTokens

Given pool token amount results in zero trading tokens

FeeCalculationFailure

The fee calculation failed due to overflow, underflow, or unexpected 0

ConversionFailure

ConversionFailure

InvalidFee

The provided fee does not match the program owner’s constraints

IncorrectTokenProgramId

The provided token program does not match the token program expected by the swap

UnsupportedCurveType

The provided curve type is not supported by the program owner

InvalidCurve

The provided curve parameters are invalid

UnsupportedCurveOperation

The operation cannot be performed on the given curve

InvalidFeeAccount

The pool fee account is invalid.

Trait Implementations

impl Clone for SwapError

fn clone(&self) -> SwapError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SwapError

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

Formats the value using the given formatter.

impl<T> DecodeError<T> for SwapError

fn type_of() -> &'static str

fn decode_custom_error_to_enum(custom: u32) -> Option<E>

where E: FromPrimitive,

impl Display for SwapError

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

impl Error for SwapError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

Converts an u64 to return an optional value of this type. If the value cannot be represented by this type, then None is returned.

fn from_isize(n: isize) -> Option<Self>

Converts an isize to return an optional value of this type. If the value cannot be represented by this type, then None is returned.

fn from_i8(n: i8) -> Option<Self>

Converts an i8 to return an optional value of this type. If the value cannot be represented by this type, then None is returned.

fn from_i16(n: i16) -> Option<Self>
