Enum RequestStatus 

pub enum RequestStatus<AccountId, Ticket> {
    Unrequested {
        ticket: (AccountId, Ticket),
        len: u32,
    },
    Requested {
        maybe_ticket: Option<(AccountId, Ticket)>,
        count: u32,
        maybe_len: Option<u32>,
    },
}

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

Variants

Unrequested

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 preimage.

Fields

ticket: (AccountId, Ticket)

len: u32

Requested

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

Fields

maybe_ticket: Option<(AccountId, Ticket)>

count: u32

maybe_len: Option<u32>

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<AccountId, Ticket> Encode for RequestStatus<AccountId, Ticket>

where AccountId: Encode, Ticket: Encode, (AccountId, Ticket): Encode, Option<(AccountId, Ticket)>: 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.
