Struct RefineContext

pub struct RefineContext {
    pub anchor: HeaderHash,
    pub state_root: StateRootHash,
    pub beefy_root: MmrPeakHash,
    pub lookup_anchor: HeaderHash,
    pub lookup_anchor_slot: Slot,
    pub prerequisites: VecSet<WorkPackageHash>,
}

Various pieces of information helpful to contextualize the Refinement process.

Fields

anchor: HeaderHash

The most recent header hash of the chain when building. This must be no more than RECENT_BLOCKS blocks old when reported.

state_root: StateRootHash

Must be state root of block anchor. This is checked on-chain when reported.

beefy_root: MmrPeakHash

Must be Beefy root of block anchor. This is checked on-chain when reported.

lookup_anchor: HeaderHash

The hash of a header of a block which is final. Availability will not succeed unless a super-majority of validators have attested to this. Preimage lookups will be judged according to this block.

NOTE: Storage pallet may not cycle more frequently than 48 hours (24 hours above plus 24 hours dispute period).

lookup_anchor_slot: Slot

The slot of lookup_anchor on the chain. This is checked in availability and the report’s package will not be made available without it being correct. This value must be at least anchor_slot + 14400.

prerequisites: VecSet<WorkPackageHash>

Hashes of Work Packages, the reports of which must be reported prior to this one. This is checked on-chain when reported.

Trait Implementations

impl Clone for RefineContext

fn clone(&self) -> RefineContext

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for RefineContext

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

Formats the value using the given formatter.

impl Decode for RefineContext

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 Encode for RefineContext

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 PartialEq for RefineContext

fn eq(&self, other: &RefineContext) -> bool

Tests for self and other values to be equal, and is used by ==.

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

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