Struct v8::SnapshotCreator [−][src]
#[repr(C)]pub struct SnapshotCreator(_);
Expand description
Helper class to create a snapshot data blob.
Implementations
Create and enter an isolate, and set it up for serialization. The isolate is created from scratch.
Set the default context to be included in the snapshot blob. The snapshot will not contain the global proxy, and we expect one or a global object template to create one, to be provided upon deserialization.
Attach arbitrary v8::Data
to the isolate snapshot, which can be
retrieved via HandleScope::get_context_data_from_snapshot_once()
after
deserialization. This data does not survive when a new snapshot is created
from an existing snapshot.

Creates a snapshot data blob. This must not be called from within a handle scope.
This is marked unsafe because it should be called at most once per snapshot creator.
