Struct BeamConstPool 

pub struct BeamConstPool { /* private fields */ }

A constant pool for BEAM modules (literal table).

BEAM stores large constants (tuples, lists, binaries) in a literal pool to avoid re-creating them on every call.

Implementations

impl BeamConstPool

pub fn new() -> Self

Create an empty constant pool.

pub fn intern(&mut self, expr: BeamExpr, key: impl Into<String>) -> u32

Intern a literal into the pool, returning its index.

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

Get a literal by index.

pub fn len(&self) -> usize

Number of literals in the pool.

pub fn is_empty(&self) -> bool

Whether the pool is empty.

Trait Implementations

impl Clone for BeamConstPool

fn clone(&self) -> BeamConstPool

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BeamConstPool

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

Formats the value using the given formatter.

impl Default for BeamConstPool

fn default() -> BeamConstPool

Returns the “default value” for a type.
