Struct polkadot_node_network_protocol::OurView

pub struct OurView { /* private fields */ }

Specialized wrapper around View.

Implementations

impl OurView

pub fn new( heads: impl IntoIterator<Item = Hash>, finalized_number: BlockNumber, ) -> Self

Creates a new instance.

Methods from Deref<Target = View>

pub fn len(&self) -> usize

Obtain the number of heads that are in view.

pub fn is_empty(&self) -> bool

Check if the number of heads contained, is null.

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

Obtain an iterator over all heads.

pub fn difference<'a>( &'a self, other: &'a View, ) -> impl Iterator<Item = &'a Hash> + 'a

Returns an iterator of the hashes present in Self but not in other.

pub fn intersection<'a>( &'a self, other: &'a View, ) -> impl Iterator<Item = &'a Hash> + 'a

An iterator containing hashes present in both Self and in other.

pub fn contains(&self, hash: &Hash) -> bool

Whether the view contains a given hash.

pub fn check_heads_eq(&self, other: &Self) -> bool

Check if two views have the same heads.

Equivalent to the PartialEq function, but ignores the finalized_number field.

Trait Implementations

impl Clone for OurView

fn clone(&self) -> OurView

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for OurView

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

Formats the value using the given formatter.

impl Default for OurView

fn default() -> OurView

Returns the “default value” for a type.

impl Deref for OurView

type Target = View

The resulting type after dereferencing.

fn deref(&self) -> &View

Dereferences the value.

impl PartialEq for OurView

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