Struct koto_parser::ConstantPool

pub struct ConstantPool { /* fields omitted */ }

A constant pool produced by the Parser for a Koto script

A ConstantPoolBuilder is used to prepare the pool.

Implementations

impl ConstantPool

pub fn size(&self) -> usize

Provides the number of constants in the pool

pub fn get(&self, index: usize) -> Option<Constant<'_>>

Returns the constant corresponding to the provided index

pub fn string_data(&self) -> &Rc<str>

Returns the concatenated string data stored in the pool

pub fn get_str(&self, index: ConstantIndex) -> &str

Returns the string corresponding to the provided index

Warning! Panics if there isn’t a string at the provided index

pub fn get_str_bounds(&self, index: ConstantIndex) -> Range<usize>

Returns bounds in the concatenated string data corresponding to the provided index

Warning! Panics if there isn’t a string at the provided index

pub fn get_f64(&self, index: ConstantIndex) -> f64

Returns the f64 corresponding to the provided constant index

Warning! Panics if there isn’t an f64 at the provided index

pub fn get_i64(&self, index: ConstantIndex) -> i64

Returns the i64 corresponding to the provided constant index

Warning! Panics if there isn’t an i64 at the provided index

pub fn iter(&self) -> ConstantPoolIterator<'_>

Provides an iterator that iterates over the pool’s constants
