[][src]Struct passerine::common::lambda::Lambda

pub struct Lambda {
    pub code: Vec<u8>,
    pub spans: Vec<(usize, Span)>,
    pub constants: Vec<Data>,
    pub captureds: Vec<usize>,

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

impl Lambda[src]

pub fn empty() -> Lambda[src]

Creates a new empty Lambda to be filled.

pub fn emit(&mut self, op: Opcode)[src]

Emits an opcode as a byte

pub fn emit_bytes(&mut self, bytes: &mut Vec<u8>)[src]

Emits a series of bytes

pub fn emit_span(&mut self, span: &Span)[src]

Emits a span, should be called before an opcode is emmited. This function ties opcodes to spans in source. See index_span as well.

pub fn demit(&mut self)[src]

Removes the last emitted byte

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

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.

pub fn index_span(&mut self, index: usize) -> Span[src]

Look up the nearest span at or before the index of a specific bytecode op.
