}Expand description
Structure representing a V8 value handle. V8 handles can only be accessed from the thread on which they are created. Valid threads for creating a V8 handle include the render process main thread (TID_RENDERER) and WebWorker threads. A task runner for posting tasks on the associated thread can be retrieved via the cef_v8_context_t::get_task_runner() function.
NOTE: This struct is allocated DLL-side.

Access to the identifier will be forwarded to the cef_v8_accessor_t instance passed to cef_v8_value_t::cef_v8_value_create_object(). Returns false (0) if this function is called incorrectly or an exception is thrown. For read-only values this function will return true (1) even though assignment failed.
get_keys: Option<unsafe extern "C" fn(self_: *mut _cef_v8_value_t, keys: cef_string_list_t) -> c_int>Read the keys for the object’s values into the specified vector. Integer- based keys will also be returned as strings.

Used to give V8 an indication of the amount of externally allocated memory that is kept alive by JavaScript objects. V8 uses this information to decide when to perform global garbage collection. Each cef_v8_value_t tracks the amount of external memory associated with it and automatically decreases the global total by the appropriate amount on its destruction. |change_in_bytes| specifies the number of bytes to adjust by.

This function should only be called from within the scope of a cef_v8_handler_t or cef_v8_accessor_t callback, or in combination with calling enter() and exit() on a stored cef_v8_context_t reference. |object| is the receiver (‘this’ object) of the function.

If |object| is NULL the specified context’s global object will be used. |arguments| is the list of arguments that will be passed to the function. Returns the function return value on success. Returns NULL if this function is called incorrectly or an exception is thrown.
resolve_promise: Option<unsafe extern "C" fn(self_: *mut _cef_v8_value_t, arg: *mut _cef_v8_value_t) -> c_int>Resolve the Promise using the current V8 context. This function should only be called from within the scope of a cef_v8_handler_t or cef_v8_accessor_t callback, or in combination with calling enter() and exit() on a stored cef_v8_context_t reference. |arg| is the argument passed to the resolved promise. Returns true (1) on success. Returns false (0) if this function is called incorrectly or an exception is thrown.
