Struct TopLevelEnvironment 

pub struct TopLevelEnvironment(/* private fields */);

A top level environment such as a library, program, or REPL.

Implementations

impl TopLevelEnvironment

pub fn new_repl(rt: &Runtime) -> Self

pub fn from_spec( rt: &Runtime, spec: LibrarySpec, path: PathBuf, ) -> Result<Self, Exception>

pub fn eval( &self, import_policy: impl Into<ImportPolicy>, code: &str, ) -> Result<Vec<Value>, Exception>

Evaluate the scheme expression in the provided environment and return the values. The import_policy controls which libraries may be imported; use ImportPolicy::Allow to permit all imports, or provide an allowlist of specific libraries.

pub fn eval_sexpr( &self, import_policy: impl Into<ImportPolicy>, sexpr: Syntax, ) -> Result<Vec<Value>, Exception>

pub fn import(&self, import_set: ImportSet) -> Result<(), Exception>

pub fn is_repl(&self) -> bool

pub fn def_var(&self, binding: Binding, name: Symbol, value: Value) -> Global

pub fn lookup_var(&self, binding: Binding) -> Result<Option<Global>, Exception>

pub fn lookup_var_inner( &self, binding: Binding, ) -> Result<Option<Global>, Exception>

pub fn def_keyword(&self, binding: Binding, transformer: Procedure)

pub fn lookup_keyword( &self, binding: Binding, ) -> Result<Option<Procedure>, Exception>

pub fn lookup_keyword_inner( &self, binding: Binding, ) -> Result<Option<Procedure>, Exception>

pub fn lookup_primitive(&self, binding: Binding) -> Option<Primitive>

Trait Implementations

impl Clone for TopLevelEnvironment

fn clone(&self) -> TopLevelEnvironment

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TopLevelEnvironment

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

Formats the value using the given formatter.

impl PartialEq for TopLevelEnvironment

fn eq(&self, rhs: &Self) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Trace for TopLevelEnvironment

unsafe fn visit_children(&self, visitor: &mut dyn FnMut(OpaqueGcPtr))
