Type Alias ExistenceReasonOf

pub type ExistenceReasonOf<T, I> = ExistenceReason<DepositBalanceOf<T, I>, <T as SystemConfig>::AccountId>;

Aliased Type

enum ExistenceReasonOf<T, I> {
    Consumer,
    Sufficient,
    DepositHeld(<<T as Config<I>>::Currency as Currency<<T as Config>::AccountId>>::Balance),
    DepositRefunded,
    DepositFrom(<T as Config>::AccountId, <<T as Config<I>>::Currency as Currency<<T as Config>::AccountId>>::Balance),
}

Variants

Consumer

A consumer reference was used to create this account.

Sufficient

The asset class is sufficient for account existence.

DepositHeld(<<T as Config<I>>::Currency as Currency<<T as Config>::AccountId>>::Balance)

The account holder has placed a deposit to exist within an asset class.

DepositRefunded

A deposit was placed for this account to exist, but it has been refunded.

DepositFrom(<T as Config>::AccountId, <<T as Config<I>>::Currency as Currency<<T as Config>::AccountId>>::Balance)

Some other AccountId has placed a deposit to make this account exist. An account with such a reason might not be referenced in system.

Trait Implementations

impl<Balance: Clone, AccountId: Clone> Clone for ExistenceReason<Balance, AccountId>

fn clone(&self) -> ExistenceReason<Balance, AccountId>

Returns a copy of the value.

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

where Balance: Decode, AccountId: Decode,

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<Balance, AccountId> Encode for ExistenceReason<Balance, AccountId>

where Balance: Encode, AccountId: Encode,

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<Balance, AccountId> MaxEncodedLen for ExistenceReason<Balance, AccountId>

where Balance: MaxEncodedLen, AccountId: MaxEncodedLen,

fn max_encoded_len() -> usize
