Struct Events

pub struct Events { /* private fields */ }

Descending sorted collection of events

Implementations

impl Events

pub fn new(filter: &Filter) -> Self

New collection

pub fn len(&self) -> usize

Returns the number of events in the collection.

pub fn is_empty(&self) -> bool

Checks if there are no events.

pub fn contains(&self, event: &Event) -> bool

Check if contains Event

pub fn insert(&mut self, event: Event) -> bool

Insert Event

If the set did not previously contain an equal value, true is returned. If the collection is full, the older events will be discarded. Use Events::force_insert to always make sure the event is inserted.

pub fn force_insert(&mut self, event: Event) -> bool

Force insert Event

Use Events::insert to respect the max collection capacity (if any). If the collection capacity is full, this method will increase it.

pub fn extend<I>(&mut self, events: I)

where I: IntoIterator<Item = Event>,

Insert events

pub fn merge(self, other: Self) -> Self

Merge events collections into a single one.

Collection is converted to unbounded if one of the merge Events have a different hash. In other words, the filters limit is respected only if the Events are related to the same list of filters.

pub fn first(&self) -> Option<&Event>

Get first Event (descending order)

pub fn first_owned(self) -> Option<Event>

Get first Event (descending order)

pub fn last(&self) -> Option<&Event>

Get last Event (descending order)

pub fn last_owned(self) -> Option<Event>

Get last Event (descending order)

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

Iterate events in descending order

pub fn to_vec(self) -> Vec<Event>

Convert the collection to vector of events.

Trait Implementations

impl Clone for Events

fn clone(&self) -> Events

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Events

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

Formats the value using the given formatter.

impl Default for Events

fn default() -> Self

Returns the “default value” for a type.

impl FromIterator<Event> for Events

fn from_iter<T>(iter: T) -> Self

where T: IntoIterator<Item = Event>,

Creates a value from an iterator.

impl IntoIterator for Events

type Item = Event

The type of the elements being iterated over.

type IntoIter = IntoIter<<Events as IntoIterator>::Item>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl PartialEq for Events

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