Struct GenerationalPool 

pub struct GenerationalPool { /* private fields */ }

A string pool that supports generational compaction.

When compact is called, unreferenced strings are removed and the generation counter is incremented, invalidating old handles.

Implementations

impl GenerationalPool

pub fn new() -> Self

Create an empty generational pool.

pub fn intern(&mut self, s: &str) -> GenerationalString

Intern a string and return a generational handle.

pub fn release(&mut self, handle: GenerationalString)

Release a handle, decrementing its reference count.

pub fn resolve(&self, handle: GenerationalString) -> Option<&str>

Resolve a handle to its string content.

pub fn is_valid(&self, handle: GenerationalString) -> bool

Check if a handle is still valid (correct generation and non-zero refcount).

pub fn compact(&mut self) -> usize

Compact the pool: remove strings with zero reference count. All handles from the previous generation are invalidated.

pub fn generation(&self) -> u16

Current generation counter.

pub fn live_count(&self) -> usize

Number of live strings (with ref_count > 0).

pub fn total_count(&self) -> usize

Total strings in the pool (including those with rc=0).

Trait Implementations

impl Default for GenerationalPool

fn default() -> Self

Returns the “default value” for a type.
