Struct rusty_v8::Context

#[repr(C)]
pub struct Context(_);

A sandboxed execution context with its own set of built-in objects and functions.

Methods

impl Context

pub fn new<'sc>(scope: &mut impl ToLocal<'sc>) -> Local<'sc, Context>

pub fn global<'sc>(
    &mut self,
    scope: &mut impl ToLocal<'sc>
) -> Local<'sc, Object>

Returns the global proxy object.

Global proxy object is a thin wrapper whose prototype points to actual context's global object with the properties like Object, etc. This is done that way for security reasons (for more details see https://wiki.mozilla.org/Gecko:SplitWindow).

Please note that changes to global proxy object prototype most probably would break VM---v8 expects only global object as a prototype of global proxy object.

pub fn enter(&mut self)

Enter this context. After entering a context, all code compiled and run is compiled and run in this context. If another context is already entered, this old context is saved so it can be restored when the new context is exited.

pub fn exit(&mut self)

Exit this context. Exiting the current context restores the context that was in place when entering the current context.

pub fn get_isolate(&mut self) -> &mut Isolate
