Fields

env: Env<C, E>

cached: FxHashMap<BindId, Value>

user: C

Implementations

impl<C: Ctx, E: UserEvent> ExecCtx<C, E>

pub fn clear(&mut self)

pub fn new_no_std(user: C) -> Self

build a new context with only the core library

pub fn new(user: C) -> Self

build a new context with the full standard library

pub fn register_builtin<T: BuiltIn<C, E>>(&mut self) -> Result<()>

pub fn set_var(&mut self, id: BindId, v: Value)

Built in functions should call this when variables are set unless they are sure the variable does not need to be cached. This will also call the user ctx set_var.
