Enum StorageValueDecodeError 

#[non_exhaustive]
pub enum StorageValueDecodeError<TypeId> {
    CannotGetInfo(StorageInfoError<'static>),
    CannotDecodeValue {
        ty: TypeId,
        reason: DecodeErrorTrace,
    },
}

An error returned trying to decode storage bytes.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

CannotGetInfo(StorageInfoError<'static>)

CannotDecodeValue

Fields

ty: TypeId

reason: DecodeErrorTrace

Implementations

impl<TypeId> StorageValueDecodeError<TypeId>

pub fn map_type_id<NewTypeId, F>( self, f: F, ) -> StorageValueDecodeError<NewTypeId>

where F: FnMut(TypeId) -> NewTypeId,

Map the storage value error type IDs to something else.

Trait Implementations

impl<TypeId: Clone> Clone for StorageValueDecodeError<TypeId>

fn clone(&self) -> StorageValueDecodeError<TypeId>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<TypeId: Debug> Debug for StorageValueDecodeError<TypeId>

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

Formats the value using the given formatter.

impl<TypeId: Debug> Display for StorageValueDecodeError<TypeId>

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

Formats the value using the given formatter.

impl<TypeId: Debug> Error for StorageValueDecodeError<TypeId>

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()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.
