Struct iroh_docs::AuthorHeads

pub struct AuthorHeads { /* private fields */ }

Timestamps of the latest entry for each author.

Implementations

impl AuthorHeads

pub fn insert(&mut self, author: AuthorId, timestamp: u64)

Insert a new timestamp.

pub fn len(&self) -> usize

Number of author-timestamp pairs.

pub fn is_empty(&self) -> bool

Whether this AuthorHeads is empty.

pub fn get(&self, author: &AuthorId) -> Option<u64>

Get the timestamp for an author.

pub fn has_news_for(&self, other: &Self) -> Option<NonZeroU64>

Can this state offer newer stuff to other?

pub fn merge(&mut self, other: &Self)

Merge another author head state into this one.

pub fn iter(&self) -> Iter<'_, AuthorId, u64>

Create an iterator over the entries in this state.

pub fn encode(&self, size_limit: Option<usize>) -> Result<Vec<u8>>

Encode into a byte array with a limited size.

Will skip oldest entries if the size limit is reached. Returns a byte array with a maximum length of size_limit.

pub fn decode(bytes: &[u8]) -> Result<Self>

Decode from byte slice created with Self::encode.

Trait Implementations

impl Clone for AuthorHeads

fn clone(&self) -> AuthorHeads

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for AuthorHeads

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

Formats the value using the given formatter.

impl Default for AuthorHeads

fn default() -> AuthorHeads

Returns the “default value” for a type.

impl FromIterator<(AuthorId, u64)> for AuthorHeads

fn from_iter<T: IntoIterator<Item = (AuthorId, u64)>>(iter: T) -> Self

Creates a value from an iterator.

impl FromIterator<(u64, AuthorId)> for AuthorHeads

fn from_iter<T: IntoIterator<Item = (u64, AuthorId)>>(iter: T) -> Self

Creates a value from an iterator.

impl PartialEq for AuthorHeads

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