Struct PoolStatistics 

pub struct PoolStatistics {
    pub unique_count: usize,
    pub unique_bytes: usize,
    pub total_intern_requests: usize,
    pub total_requested_bytes: usize,
}

Statistics for a StringPool.

Fields

unique_count: usize

Number of unique strings stored.

unique_bytes: usize

Total bytes of unique string data stored.

total_intern_requests: usize

Total number of intern requests (including duplicates).

total_requested_bytes: usize

Total bytes that would have been stored without deduplication.

Implementations

impl PoolStatistics

pub fn bytes_saved(&self) -> usize

Bytes saved by deduplication.

pub fn dedup_ratio(&self) -> f64

Deduplication ratio (0.0 to 1.0). Returns 0.0 if no bytes were requested.

pub fn avg_string_len(&self) -> f64

Average string length.

Trait Implementations

impl Clone for PoolStatistics

fn clone(&self) -> PoolStatistics

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PoolStatistics

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

Formats the value using the given formatter.

impl Default for PoolStatistics

fn default() -> PoolStatistics

Returns the “default value” for a type.

impl Display for PoolStatistics

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

Formats the value using the given formatter.

impl PartialEq for PoolStatistics

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