Struct StringStore 

pub struct StringStore<'a> { /* private fields */ }

Arena-allocated string pool with heap fallback for long strings.

Index 0 is a sentinel representing the empty string (no entry is stored for it). All stored strings receive 1-based indices.

Implementations

impl<'a> StringStore<'a>

pub fn new(arena: &'a Bump) -> Self

Creates a new empty string store backed by the given arena.

pub fn store(&mut self, s: &str) -> u32

Stores a string and returns its 1-based index.

Strings up to [SHORT_THRESHOLD] bytes are copied into the arena; longer strings are heap-allocated.

pub fn get(&self, idx: u32) -> &str

Returns the string at the given index.

Index 0 returns "" (empty-string sentinel). Other indices are 1-based into the internal storage.

Panics

Panics if idx is out of range (greater than the number of stored strings).
