Struct Compiler 

pub struct Compiler { /* private fields */ }

The bytecode compiler.

Compiles a single expression (which may contain nested lambdas) into a top-level Chunk. Nested lambdas produce sub-chunks stored in the constant pool.

The compiler maintains a shared Interner that is also passed to the VM for attribute key resolution.

Implementations

impl Compiler

pub fn compile_with_base_dir( input: &str, base_dir: PathBuf, ) -> Result<(Chunk, Interner), CompileError>

Compile a Nix expression string into bytecode and an interner, resolving relative paths against the given base directory.

pub fn compile_with_shared_interner( input: &str, base_dir: PathBuf, interner: Rc<RefCell<Interner>>, ) -> Result<Chunk, CompileError>

Compile using a shared interner and base directory. Used when importing files from within the VM so that symbol IDs are consistent with the VM’s interner.

pub fn compile_expression( input: &str, base_dir: &Path, interner: Rc<RefCell<Interner>>, ) -> Result<Chunk, CompileError>

Compile a standalone expression string (used for lazy thunk compilation). The expression is parsed and compiled fresh with the given interner and base directory.

pub fn compile(input: &str) -> Result<(Chunk, Interner), CompileError>

Compile a Nix expression string into bytecode and an interner.
