Enum sp_runtime::traits::StoredMapError

pub enum StoredMapError {
    NoProviders,
    ConsumerRemaining,
}

Error that can be returned by our impl of StoredMap.

Variants

NoProviders

Attempt to create map value when it is a consumer and there are no providers in place.

ConsumerRemaining

Attempt to anull/remove value when it is the last provider and there is still at least one consumer left.

Trait Implementations

impl Debug for StoredMapError

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

impl Decode for StoredMapError

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

Attempt to deserialise the value from input.

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

Attempt to skip the encoded value from input.

pub fn encoded_fixed_size() -> Option<usize>

Returns the fixed encoded size of the type.

impl Encode for StoredMapError

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