Implementations§

Source§

impl<R: Rt, E: UserEvent> ExecCtx<R, E>

Source

pub fn clear(&mut self)

Source

pub fn new(user: R) -> Self

Build a new execution context.

This is a very low level interface that you can use to build a custom runtime with deep integration to your code. It is very difficult to use, and if you don’t implement everything correctly the semantics of the language can be wrong.

Most likely you want to use the rt module instead.

Source

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

Source

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.

Source

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

Source

pub fn with_restored<T, F: FnOnce(&mut Self) -> T>( &mut self, env: Env<R, E>, f: F, ) -> T

Restore the lexical environment to the snapshot env for the duration of f restoring it to it’s original value afterwords. by_id and lambdas defined by the closure will be retained.
