Struct HistorySeenFrontier 

pub struct HistorySeenFrontier { /* private fields */ }

Implementations

impl HistorySeenFrontier

pub fn from_hex(ids: impl IntoIterator<Item = String>) -> HistorySeenFrontier

pub fn to_hex(&self) -> Vec<String>

Stable sorted form for private settings persistence.

pub fn contains(&self, id: &HistoryEntryId) -> bool

pub fn unread_count(&self, entries: &[HistoryEntry]) -> usize

pub fn unseen<'a>(&self, entries: &'a [HistoryEntry]) -> Vec<&'a HistoryEntry>

pub fn mark_seen(&mut self, entries: &[HistoryEntry])

Replace, rather than append, because history sources are deliberately bounded. Ids outside the current retention window cannot become visible again without a cold-history source supplying them as entries.

Trait Implementations

impl Clone for HistorySeenFrontier

fn clone(&self) -> HistorySeenFrontier

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for HistorySeenFrontier

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

Formats the value using the given formatter.

impl Default for HistorySeenFrontier

fn default() -> HistorySeenFrontier

Returns the “default value” for a type.

impl PartialEq for HistorySeenFrontier

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