Struct jormungandr::blockchain::checkpoints::Checkpoints

pub struct Checkpoints(Vec<HeaderHash>);

list of pre-computed checkpoints from a given Ref.

Tuple Fields

0: Vec<HeaderHash>

Implementations

impl Checkpoints

pub fn new_from(from: Arc<Ref>) -> Self

create a new list of checkpoints from the given starting point (tip).

The function make use of the Ref object pointing to previous epoch in order to populate interestingly spaced checkpoints.

For now the algorithm provide the current block, the parent, the last block of the previous epoch, the last block of the epoch before that… until the block0.

pub fn iter(&self) -> impl Iterator<Item = &HeaderHash>

pub fn as_slice(&self) -> &[HeaderHash]

Trait Implementations

impl AsRef<[Hash]> for Checkpoints

fn as_ref(&self) -> &[HeaderHash]

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for Checkpoints

fn clone(&self) -> Checkpoints

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Checkpoints

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

Formats the value using the given formatter.

impl From<Checkpoints> for Vec<HeaderHash>

fn from(checkpoints: Checkpoints) -> Self

Converts to this type from the input type.

impl IntoIterator for Checkpoints

type Item = Hash

The type of the elements being iterated over.

type IntoIter = IntoIter<<Checkpoints as IntoIterator>::Item, Global>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl PartialEq<Checkpoints> for Checkpoints

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