}

Every error that can be returned to a contract when it calls any of the host functions.

Variants

Success = 0

API call successful.

CalleeTrapped = 1

The called function trapped and has its state changes reverted. In this case no output buffer is returned. Can only be returned from call and instantiate.

CalleeReverted = 2

The called function ran to completion but decided to revert its state. An output buffer is returned when one was supplied. Can only be returned from call and instantiate.

KeyNotFound = 3

The passed key does not exist in storage.

TransferFailed = 4

Transfer failed for other not further specified reason. Most probably reserved or locked balance of the sender that was preventing the transfer.

OutOfResources = 5

The subcall ran out of weight or storage deposit.

EcdsaRecoveryFailed = 7

ECDSA public key recovery failed. Most probably wrong recovery id or signature.

Sr25519VerifyFailed = 8

sr25519 signature verification failed.

DuplicateContractAddress = 11

Contract instantiation failed because the address already exists. Occurs when instantiating the same contract with the same salt more than once.

Unknown = 12

Returns if an unknown error was received from the host module.

Trait Implementations

impl Debug for ReturnErrorCode

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

Formats the value using the given formatter.

impl PartialEq for ReturnErrorCode

fn eq(&self, other: &ReturnErrorCode) -> bool

Tests for self and other values to be equal, and is used by ==.

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

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