Enum ContractAccessError

pub enum ContractAccessError {
    DoesntExist,
    KeyDecodingFailed,
    MigrationInProgress,
}

The possible errors that can happen querying the storage of a contract.

Variants

DoesntExist

The given address doesn’t point to a contract.

KeyDecodingFailed

Storage key cannot be decoded from the provided input data.

MigrationInProgress

Storage is migrating. Try again later.

Trait Implementations

impl Clone for ContractAccessError

fn clone(&self) -> ContractAccessError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ContractAccessError

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

Formats the value using the given formatter.

impl Decode for ContractAccessError

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 Encode for ContractAccessError

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 MaxEncodedLen for ContractAccessError

fn max_encoded_len() -> usize

Upper bound, in bytes, of the maximum encoded size of this item.

impl PartialEq for ContractAccessError

fn eq(&self, other: &ContractAccessError) -> 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.

impl TypeInfo for ContractAccessError

type Identity = ContractAccessError

The type identifying for which type info is provided.

fn type_info() -> Type

Returns the static type identifier for Self.

impl Copy for ContractAccessError

impl EncodeLike for ContractAccessError
