Struct passerine::compiler::gen::Chunk

pub struct Chunk {
    pub code: Vec<u8>,
    pub offsets: Vec<usize>,
    pub constants: Vec<Data>,
    pub locals: Vec<Local>,
}

Represents a single interpretable chunk of bytecode, Think a function.

Fields

code: Vec<u8>

offsets: Vec<usize>

constants: Vec<Data>

locals: Vec<Local>

Implementations

impl Chunk

pub fn empty() -> Chunk

Creates a new empty chunk to be filled.

pub fn index_data(&mut self, data: Data) -> usize

Given some data, this function adds it to the constants table, and returns the data's index. The constants table is push only, so constants are identified by their index. The resulting usize can be split up into a number byte stream, and be inserted into the bytecode.

Trait Implementations

impl Clone for Chunk

fn clone(&self) -> Chunk

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Chunk

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

Formats the value using the given formatter.

impl Eq for Chunk

impl PartialEq<Chunk> for Chunk

fn eq(&self, other: &Chunk) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Chunk) -> bool

This method tests for !=.

impl StructuralEq for Chunk

impl StructuralPartialEq for Chunk
