branch: Vec<BlockHash>

number: BlockNumber

Implementations

impl PhronProposal

pub fn len(&self) -> usize

Outputs the length the branch.

pub fn top_block(&self) -> BlockId

Outputs the highest block in the branch.

pub fn bottom_block(&self) -> BlockId

Outputs the lowest block in the branch.

pub fn number_below_branch(&self) -> BlockNumber

Outputs the number one below the lowest block in the branch.

pub fn number_bottom_block(&self) -> BlockNumber

Outputs the number of the lowest block in the branch.

pub fn number_top_block(&self) -> BlockNumber

Outputs the number of the highest block in the branch.

pub fn block_at_num(&self, num: BlockNumber) -> Option<BlockId>

Outputs the block corresponding to the number in the proposed branch in case num is between the lowest and highest block number of the branch. Otherwise returns None.

pub fn blocks_from_num( &self, num: BlockNumber ) -> impl Iterator<Item = BlockId> + '_

Outputs an iterator over blocks starting at num. If num is too high, the iterator is empty, if it’s too low the whole branch is returned.

Trait Implementations

impl Clone for PhronProposal

fn clone(&self) -> PhronProposal

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PhronProposal

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

Formats the value using the given formatter.

impl Decode for PhronProposal

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 PhronProposal

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 Hash for PhronProposal

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Index<usize> for PhronProposal

type Output = <Header<u32, BlakeTwo256> as Header>::Hash

The returned type after indexing.

fn index(&self, index: usize) -> &Self::Output

Performs the indexing (container[index]) operation.

impl PartialEq for PhronProposal

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