Struct Context

pub struct Context;

The Context provided by this crate.

Implementations

impl Context

pub fn apply( func: Gc<Value<Self>>, args: Vec<Gc<Value<Self>>>, ) -> Result<Gc<Value<Self>>, RuntimeError>

Applies a function to the given arguments.

Trait Implementations

impl Clone for Context

fn clone(&self) -> Context

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl CompilerContext for Context

type CompileError = CompileError

An error encountered during compilation.

fn compile( main_module: Symbol, exported_modules: HashMap<Symbol, ExportedModule<Self>>, ) -> Result<Vec<u8>, Self::CompileError>

Compiles a module.

impl Context for Context

type BuiltinFunction = fn(Vec<Gc<Value<Context>>>) -> Result<Gc<Value<Context>>, RuntimeError>

The type of a function implemented by the runtime.

type Expr = Expr

The type of an expression in the AST.

type ObjectVtable = HashMap<Symbol, Gc<Value<Context>>>

The type of the vtable of an object.

type UserFunction = (Gc<Expr>, GcLinkedList<(Symbol, Gc<Value<Context>>)>)

The type of a user function. This probably should just be the arguments (as an Args<C>), the body (as C::Expr), and the variables closed over and their values (as a GcLinkedList<(Symbol, Value<C>)>).

type ValueMeta = ()

The metadata attached to the value.

fn from_expr(expr: Gc<AstExpr<Self>>) -> Gc<Expr>

Converts a standard ast::Expr to the expression type of the context.

impl Debug for Context

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

Formats the value using the given formatter.

impl Drop for Context

fn drop(&mut self)

Executes the destructor for this type.

impl Finalize for Context

fn finalize(&self)

impl InterpreterContext for Context

type RuntimeError = RuntimeError

An error encountered at runtime.

fn eval( expr: Gc<Expr>, env: &mut GcLinkedList<(Symbol, Gc<Value<Self>>)>, ) -> Result<Gc<Value<Self>>, RuntimeError>

Evaluates an expression.

fn primitives() -> HashMap<Symbol, Gc<Value<Self>>>

Returns the values in the std/internal/primitives module.

impl Trace for Context

unsafe fn trace(&self)

Marks all contained Gcs.

unsafe fn root(&self)

Increments the root-count of all contained Gcs.

unsafe fn unroot(&self)

Decrements the root-count of all contained Gcs.

fn finalize_glue(&self)

Runs Finalize::finalize() on this object and all contained subobjects
