Struct InternPool 

pub struct InternPool { /* private fields */ }

String interning pool for deduplication

Implementations

impl InternPool

pub fn new() -> Self

Create a new empty intern pool

pub fn with_capacity(capacity: usize) -> Self

Create a pool with pre-allocated capacity

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

Intern a string, returning its pool index

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

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

Get a string by its pool index

pub fn len(&self) -> usize

Get the number of unique strings in the pool

pub fn is_empty(&self) -> bool

Check if the pool is empty

pub fn serialize(&self) -> Vec<u8>

Serialize the pool to bytes

Format:

• Pool size: u32 (total bytes for pool section)
• String count: u32
• Offsets: [u32; count] (byte offset of each string in data section)
• Data: concatenated UTF-8 strings

pub fn deserialize(bytes: &[u8]) -> Result<(Self, usize), InternError>

Deserialize a pool from bytes

Returns the pool and the number of bytes consumed.

Trait Implementations

impl Default for InternPool

fn default() -> Self

Returns the “default value” for a type.
