Struct Chunk

pub struct Chunk {
    pub code: Vec<u8>,
    pub constants: Vec<Value>,
    pub lines: Vec<usize>,
    pub identifiers: Vec<String>,
}

A chunk of bytecode representing a compiled program

Fields

code: Vec<u8>

The actual bytecode instructions

constants: Vec<Value>

Constant values used by the program

lines: Vec<usize>

Source code line numbers for debugging

identifiers: Vec<String>

Variable and function names used in the program

Implementations

impl Chunk

pub fn new() -> Self

Creates a new, empty bytecode chunk

pub fn write_byte(&mut self, byte: u8, line: usize)

Writes a byte to the chunk

Arguments

• byte - The byte to write
• line - The source code line number

pub fn write_op(&mut self, op: OpCode, line: usize)

Writes an opcode to the chunk

Arguments

• op - The opcode to write
• line - The source code line number

pub fn add_constant(&mut self, value: Value) -> usize

Adds a constant to the chunk’s constant pool

Arguments

• value - The constant value to add

Returns

The index of the constant in the constant pool

pub fn add_identifier(&mut self, name: String) -> usize

Adds an identifier to the chunk’s identifier pool

Arguments

• name - The identifier name to add

Returns

The index of the identifier in the identifier pool

pub fn serialize(&self, writer: &mut dyn Write) -> Result<()>

Serializes the chunk to binary data

Arguments

• writer - The writer to write the binary data to

Returns

IO result indicating success or failure

pub fn deserialize(reader: &mut dyn Read) -> Result<Self>

Deserializes a chunk from binary data

Arguments

• reader - The reader to read the binary data from

Returns

The deserialized chunk or an IO error
