Implementations

impl Solution

pub fn genesis_solution() -> Self

Fake solution for the genesis block

pub fn verify_full<PotVerifier>( &self, slot: SlotNumber, params: &SolutionVerifyFullParams, ) -> Result<(), SolutionVerifyError>

where PotVerifier: SolutionPotVerifier,

Check solution validity

pub fn verify_stateless<PotVerifier>( &self, slot: SlotNumber, params: &SolutionVerifyStatelessParams, ) -> Result<(), SolutionVerifyError>

where PotVerifier: SolutionPotVerifier,

Stateless solution verification.

Checks most things, except checking that the piece belongs to the global history.

For piece verification use Self::verify_piece() or call Self::verify_full() for more efficient verification of both at once.

pub fn verify_piece( &self, piece_check_params: &SolutionVerifyPieceParams, ) -> Result<(), SolutionVerifyError>

Verify the piece details of the solution

Trait Implementations

impl Clone for Solution

fn clone(&self) -> Solution

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Solution

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

Formats the value using the given formatter.

impl Decode for Solution

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<'de> Deserialize<'de> for Solution

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Encode for Solution

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 Solution

fn max_encoded_len() -> usize

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

impl PartialEq for Solution

fn eq(&self, other: &Solution) -> 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 Serialize for Solution

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
