Struct opentelemetry::sdk::trace::EvictedHashMap

pub struct EvictedHashMap { /* fields omitted */ }

This is supported on crate feature trace only.

A hash map with a capped number of attributes that retains the most recently set entries.

Implementations

impl EvictedHashMap

pub fn new(max_len: u32, capacity: usize) -> Self

Create a new EvictedHashMap with a given max length and capacity.

pub fn insert(&mut self, item: KeyValue)

Inserts a key-value pair into the map.

pub fn len(&self) -> usize

Returns the number of elements in the map.

pub fn is_empty(&self) -> bool

Returns true if the map is empty.

pub fn dropped_count(&self) -> u32

Returns the dropped attribute count

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

Returns a front-to-back iterator.

pub fn get(&self, key: &Key) -> Option<&Value>

Returns a reference to the value corresponding to the key if it exists
