Struct rusty_v8::Context

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

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

Implementations

impl Context

pub fn new<'s>(scope: &mut HandleScope<'s, ()>) -> Local<'s, Context>

Creates a new context.

pub fn new_from_template<'s>(
    scope: &mut HandleScope<'s, ()>,
    templ: Local<'_, ObjectTemplate>
) -> Local<'s, Context>

Creates a new context using the object template as the template for the global object.

pub fn global<'s>(&self, scope: &mut HandleScope<'s, ()>) -> Local<'s, 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.

Methods from Deref<Target = Data>

pub fn get_hash(&self) -> int

Returns the V8 hash value for this value. The current implementation uses a hidden property to store the identity hash on some object types.

The return value will never be 0. Also, it is not guaranteed to be unique.

pub fn is_value(&self) -> bool

Returns true if this data is a Value.

pub fn is_module(&self) -> bool

Returns true if this data is a Module.

pub fn is_private(&self) -> bool

Returns true if this data is a Private.

pub fn is_object_template(&self) -> bool

Returns true if this data is an ObjectTemplate

pub fn is_function_template(&self) -> bool

Returns true if this data is a FunctionTemplate.

Trait Implementations

impl Debug for Context

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

Formats the value using the given formatter.

impl Deref for Context

type Target = Data

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl Hash for Context

fn hash<H: Hasher>(&self, state: &mut H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H) where
    H: Hasher, 

Feeds a slice of this type into the given Hasher.

impl<'s> PartialEq<Context> for Data

fn eq(&self, other: &Context) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=.

impl<'s> PartialEq<Context> for Context

fn eq(&self, other: &Context) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=.

impl<'s> PartialEq<Data> for Context

fn eq(&self, other: &Data) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=.
