Struct StringInterner 

pub struct StringInterner { /* private fields */ }

Thread-safe string interner for deduplicating repeated string values

This implementation uses Arc to share string data across multiple references, significantly reducing memory usage when the same strings appear multiple times (common in BPSV config files).

Implementations

impl StringInterner

pub fn new() -> Self

Create a new string interner

pub fn with_capacity(capacity: usize) -> Self

Create a new string interner with pre-allocated capacity

pub fn intern(&self, s: &str) -> Arc<String>

Intern a string, returning an Arc to the shared instance

If the string already exists in the pool, returns the existing Arc. Otherwise, adds it to the pool and returns a new Arc.

pub fn intern_owned(&self, s: String) -> Arc<String>

Intern a string that we already own

pub fn unique_count(&self) -> usize

Get the number of unique strings in the pool

pub fn memory_usage(&self) -> MemoryStats

Get memory statistics

pub fn clear(&self)

Clear the interner pool

pub fn hit_rate(&self) -> f64

Get hit rate statistics

Trait Implementations

impl Clone for StringInterner

fn clone(&self) -> StringInterner

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StringInterner

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

Formats the value using the given formatter.

impl Default for StringInterner

fn default() -> Self

Returns the “default value” for a type.
