Enum pallet_preimage::RequestStatus

pub enum RequestStatus<AccountId, Balance> {
    Unrequested(Option<(AccountId, Balance)>),
    Requested(u32),
}

A type to note whether a preimage is owned by a user or the system.

Variants

Unrequested(Option<(AccountId, Balance)>)

The associated preimage has not yet been requested by the system. The given deposit (if some) is being held until either it becomes requested or the user retracts the primage.

Requested(u32)

There are a non-zero number of outstanding requests for this hash by this chain. If there is a preimage registered, then it may be removed iff this counter becomes zero.

Trait Implementations

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

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

Returns a copy of the value.

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

Performs copy-assignment from source.

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

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

Formats the value using the given formatter.

impl<AccountId, Balance> Decode for RequestStatus<AccountId, Balance>where
    Option<(AccountId, Balance)>: Decode,

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

Attempt to deserialise the value from input.

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<AccountId, Balance> Encode for RequestStatus<AccountId, Balance>where
    Option<(AccountId, Balance)>: Encode,

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

Convert self to a slice and append it to the destination.

fn size_hint(&self) -> usize

If possible give a hint of expected size of the encoding.

fn encode(&self) -> Vec<u8, Global>

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<AccountId, Balance> MaxEncodedLen for RequestStatus<AccountId, Balance>where
    Option<(AccountId, Balance)>: MaxEncodedLen,

fn max_encoded_len() -> usize

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

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

fn eq(&self, other: &RequestStatus<AccountId, Balance>) -> 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.

    Option<(AccountId, Balance)>: TypeInfo + 'static,
    AccountId: TypeInfo + 'static,
    Balance: TypeInfo + 'static,

type Identity = RequestStatus<AccountId, Balance>

The type identifying for which type info is provided.

fn type_info() -> Type

Returns the static type identifier for Self.
