Struct HeavyHitter 

pub struct HeavyHitter<K> {
    pub rank: u32,
    pub key: K,
    pub estimate: u64,
    pub error: u64,
}

Scored entry returned by SpaceSaving::top_k. K carries the caller’s key type so the report keeps the original identifier (no hash collision on IP addresses, flow tuples, etc.).

Fields

rank: u32

Rank in the top-K (0 = highest estimate).

key: K

Caller-supplied key.

estimate: u64

Frequency estimate (always ≥ true_count).

error: u64

Worst-case overestimate (estimate − true_count upper-bound).

Trait Implementations

impl<K: Clone> Clone for HeavyHitter<K>

fn clone(&self) -> HeavyHitter<K>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<K: Debug> Debug for HeavyHitter<K>

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

Formats the value using the given formatter.

impl<'de, K> Deserialize<'de> for HeavyHitter<K>

where K: Deserialize<'de>,

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<K: PartialEq> PartialEq for HeavyHitter<K>

fn eq(&self, other: &HeavyHitter<K>) -> 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.

impl<K> Serialize for HeavyHitter<K>

where K: Serialize,

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
