Struct PotNextSlotInput

pub struct PotNextSlotInput {
    pub slot: Slot,
    pub slot_iterations: NonZeroU32,
    pub seed: PotSeed,
}

Next slot input for proof of time evaluation

Fields

slot: Slot

Slot

slot_iterations: NonZeroU32

Slot iterations for this slot

seed: PotSeed

Seed for this slot

Implementations

impl PotNextSlotInput

pub fn derive( base_slot_iterations: NonZeroU32, parent_slot: Slot, parent_output: PotOutput, pot_parameters_change: &Option<PotParametersChange>, ) -> Self

Derive next slot input while taking parameters change into account.

NOTE: base_slot_iterations doesn’t have to be parent block, just something that is after prior parameters change (if any) took effect, in most cases this value corresponds to parent block’s slot.

Trait Implementations

impl Clone for PotNextSlotInput

fn clone(&self) -> PotNextSlotInput

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PotNextSlotInput

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

Formats the value using the given formatter.

impl Decode for PotNextSlotInput

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 PotNextSlotInput

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 MaxEncodedLen for PotNextSlotInput

fn max_encoded_len() -> usize

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

impl PartialEq for PotNextSlotInput

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

impl TypeInfo for PotNextSlotInput

type Identity = PotNextSlotInput

The type identifying for which type info is provided.

fn type_info() -> Type

Returns the static type identifier for Self.
