Struct frame_support::traits::tokens::fungible::LoneFreezeConsideration

pub struct LoneFreezeConsideration<A, Fx, Rx, D, Fp>(/* private fields */);

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

NOTE: This is an optimized implementation, which can only be used for systems where each account has only a single active ticket associated with it since individual tickets do not track the specific balance which is frozen. If you are uncertain then use FreezeConsideration instead, since this works in all circumstances.

Trait Implementations

impl<A, Fx, Rx, D, Fp> Clone for LoneFreezeConsideration<A, Fx, Rx, D, Fp>

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, Fx: 'static + MutateFreeze<A> + Mutate<A>, Rx: 'static + Get<Fx::Id>, D: 'static + Convert<Fp, Fx::Balance>, Fp: 'static> Consideration<A, Fp> for LoneFreezeConsideration<A, Fx, Rx, 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, Fx, Rx, D, Fp> Debug for LoneFreezeConsideration<A, Fx, Rx, D, Fp>

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

Formats the value using the given formatter.

impl<A, Fx, Rx, D, Fp> Decode for LoneFreezeConsideration<A, Fx, Rx, D, Fp>

where PhantomData<fn() -> (A, Fx, Rx, D, Fp)>: 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<A, Fx, Rx, D, Fp> Encode for LoneFreezeConsideration<A, Fx, Rx, D, Fp>

where PhantomData<fn() -> (A, Fx, Rx, 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<__CodecOutputReturn, __CodecUsingEncodedCallback: FnOnce(&[u8]) -> __CodecOutputReturn>( &self, f: __CodecUsingEncodedCallback, ) -> __CodecOutputReturn

Convert self to a slice and then invoke the given closure with it.

fn encoded_size(&self) -> usize

Calculates the encoded size.

impl<A, Fx, Rx, D, Fp> MaxEncodedLen for LoneFreezeConsideration<A, Fx, Rx, D, Fp>

fn max_encoded_len() -> usize

impl<A, Fx, Rx, D, Fp> PartialEq for LoneFreezeConsideration<A, Fx, Rx, D, Fp>

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.
