Changes signature of "FunctionTemplate::build_fast" to allow
to pass "CFunctionInfo" explicitly. If it's not passed explicitly,
it's still autogenerated.
Adds bindings for:
- v8::Context::GetContinuationPreservedEmbedderData
- v8::Context::SetContinuationPreservedEmbedderData
These APIs are available on the "HandleScope".

Removing this garbage collection trigger removes the guarantee that
"regular" FinalizerCallbacks will be called before the isolate goes away.
It is fine as both spec and V8 do not provide this guarantee and we were
overly strict in this case.
The pointer returned by `ArrayBuffer::data` might be null if the
backing store has zero length, but the return type `*mut c_void` does
not force the user to consider this case. This change makes the return
type `Option<NonNull<c_void>>`, which is semantically equivalent, but
which forces users of the API to handle the `None` case.
This PR is the `ArrayBuffer` counterpart to #817.
This is a breaking API change.
This method, introduced in V8 10.9, makes it so an `ArrayBuffer`
object is impossible to detach unless a specific detach key is passed
to the `detach` method. Such `ArrayBuffer`s still count as detachable
as per the `ArrayBuffer::is_detachable` method, but otherwise behave
much like WebAssembly memories.
This commit adds "v8::Module::get_stalled_top_level_await_message" API
that allows to retrieve a vector of tuples with handles to v8::Module and v8::Message.
This information can be used to display a nice error when event loop runs out
of work to do but there are still unresolved promises.
This commit adds "v8::Isolate::snapshot_creator_from_existing_snapshot" API,
that allows to create a new snapshot from already existing snapshot.
Following APIs were added as well:
"v8::Context::from_snapshot"
"v8::Isolate::add_context"

This commit removes "v8::SnapshotCreator" in favor of
"v8::Isolate::snapshot_creator" API. All methods from
"v8::SnapshotCreator" are now available on the "v8::Isolate".
If a method is called and isolate was not set up as a snapshot
creator then it will panic.
This commit gets rid of long standing unsoundness in typing
that allowed to easily induce a panic or segfault if a user didn't
use snapshot creator API properly.
Check that it actually performs the expected operation (adding two
numbers) because it didn't - the callback's function prototype was
wrong. V8 always passes the receiver object as the first parameter.
Currently, when a finalizer callback is registered, it is not
guaranteed to be called if there is a global reference to the
corresponding object that survives the isolate. This is because the
finalizer callback takes a `&mut Isolate`, and so it must be called
before the isolate is fully destroyed, but all existing globals
(including possibly the one being currently finalized) are still
usable while there still exists a mutable reference to the isolate.
However, there are still use cases for having finalizers that are
guaranteed to run regardless of any remaining globals, but that don't
require any interaction with the isolate. This change adds them.
This change also changes the context annex to use a guaranteed
finalizer, fixing a bug with context slots not being freed if there
were any globals to the context at the time the isolate is dropped.
property_attribute previously had an addition operator overload which
doesn't make much sense in comparison to the corresponding V8
enumeration. This changes that to a bitor overload.

This change allows the customization of the behavior of
v8::Object::GetOwnPropertyNames() and v8::Object::GetPropertyNames() by
accepting all the options that the raw V8 API supports.
