Struct BytecodeCompiler

pub struct BytecodeCompiler { /* private fields */ }

Compiles JavaScript source code into bytecode.

use jsyc_compiler::{JSSourceCode, BytecodeCompiler};

let js_code = JSSourceCode::new("console.log('Hello World');".into());
let mut compiler = BytecodeCompiler::new();

let bytecode = compiler.compile(&js_code).expect("Failed to compile code");
println!("bytecode: {}", bytecode);

Implementations

impl BytecodeCompiler

pub fn new() -> Self

Creates a new bytecode compiler

pub fn add_var_decl(&mut self, decl: String) -> CompilerResult<Reg>

Add a variable decleration to the compiler

By adding a variable declaration, you can inform the compiler about the existence of an external declaration. However, this is not necessary since dependencies are tracked and can be retrieved after the compilation through decl_dependencies.

pub fn decl_dependencies(&self) -> &DeclDepencies

Returns all dependencies on external declarations

Usually JavaScript depends on several function and variable declarations from outside of the current script: such as window, document or setInterval.

Returns

A list of these dependencies and in which register they are expected to be. This result will be available after BytecodeCompiler::compile ran.

pub fn compile(&mut self, source: &JSSourceCode) -> BytecodeResult

Compiles the provided JavaScript code into bytecode.

use jsyc_compiler::{JSSourceCode, BytecodeCompiler};

let js_code = JSSourceCode::new("console.log('Hello World');".into());
let mut compiler = BytecodeCompiler::new();

let bytecode = compiler.compile(&js_code).expect("Failed to compile code");
println!("bytecode: {}", bytecode);

Trait Implementations

impl Clone for BytecodeCompiler

fn clone(&self) -> BytecodeCompiler

Returns a copy of the value.

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

Performs copy-assignment from source.
