Struct frame_support::traits::tokens::fungible::FreezeConsideration

pub struct FreezeConsideration<A, F, R, D, Fp>(/* private fields */)
where
    F: MutateFreeze<A>;

Consideration method using a fungible balance frozen as the cost exacted for the footprint.

The aggregate amount frozen under R::get() for any account which has multiple tickets, is the cumulative amounts of each ticket’s footprint (each individually determined by D).

Trait Implementations

impl<A, F, R, D, Fp> Clone for FreezeConsideration<A, F, R, D, Fp>

where F: MutateFreeze<A>,

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<A: 'static + Eq, F: 'static + MutateFreeze<A> + Mutate<A>, R: 'static + Get<F::Id>, D: 'static + Convert<Fp, F::Balance>, Fp: 'static> Consideration<A, Fp> for FreezeConsideration<A, F, R, D, Fp>

fn new(who: &A, footprint: Fp) -> Result<Self, DispatchError>

Create a ticket for the new footprint attributable to who. This ticket must ultimately be consumed through update or drop once the footprint changes or is removed.

fn update(self, who: &A, footprint: Fp) -> Result<Self, DispatchError>

Optionally consume an old ticket and alter the footprint, enforcing the new cost to who and returning the new ticket (or an error if there was an issue).

fn drop(self, who: &A) -> Result<(), DispatchError>

Consume a ticket for some old footprint attributable to who which should now been freed.

fn ensure_successful(who: &A, fp: Fp)

Ensure that creating a ticket for a given account and footprint will be successful if done immediately after this call.

fn burn(self, _: &AccountId)

Consume a ticket for some old footprint attributable to who which should be sacrificed.

impl<A, F, R, D, Fp> Debug for FreezeConsideration<A, F, R, D, Fp>

where F: MutateFreeze<A>,

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

Formats the value using the given formatter.

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.

where F: MutateFreeze<A>, F::Balance: Encode, PhantomData<fn() -> (A, R, D, Fp)>: 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<A, F, R, D, Fp> MaxEncodedLen for FreezeConsideration<A, F, R, D, Fp>

where F: MutateFreeze<A>,

fn max_encoded_len() -> usize

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

impl<A: 'static + Eq, F: 'static + MutateFreeze<A> + Mutate<A>, R: 'static + Get<F::Id>, D: 'static + Convert<Fp, F::Balance>, Fp: 'static> MaybeConsideration<A, Fp> for FreezeConsideration<A, F, R, D, Fp>

fn is_none(&self) -> bool

Returns true if this Consideration represents a no-cost ticket and can be forgotten without any side effects.

impl<A, F, R, D, Fp> PartialEq for FreezeConsideration<A, F, R, D, Fp>

where F: MutateFreeze<A>,

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