Enum pallet_assets::ExistenceReason

pub enum ExistenceReason<Balance, AccountId> {
    Consumer,
    Sufficient,
    DepositHeld(Balance),
    DepositRefunded,
    DepositFrom(AccountId, Balance),
}

The reason for an account’s existence within an asset class.

Variants

Consumer

A consumer reference was used to create this account.

Sufficient

The asset class is sufficient for account existence.

DepositHeld(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(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)

Performs copy-assignment from source.

impl<Balance, AccountId> Debug for ExistenceReason<Balance, AccountId>where Balance: Debug, AccountId: Debug,

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

Formats the value using the given formatter.

impl<Balance, AccountId> Decode for ExistenceReason<Balance, AccountId>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) -> Rwhere 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

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

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

fn eq(&self, other: &ExistenceReason<Balance, AccountId>) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

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

impl<Balance, AccountId> TypeInfo for ExistenceReason<Balance, AccountId>where Balance: TypeInfo + 'static, AccountId: TypeInfo + 'static,

type Identity = ExistenceReason<Balance, AccountId>

The type identifying for which type info is provided.

fn type_info() -> Type

Returns the static type identifier for Self.
