Structure representing a V8 context 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.

Fields

base: cef_base_ref_counted_t

Base structure.

get_task_runner: Option<unsafe extern "C" fn(self_: *mut _cef_v8_context_t) -> *mut _cef_task_runner_t>

Returns the task runner associated with this context. V8 handles can only be accessed from the thread on which they are created. This function can be called on any render process thread.

is_valid: Option<unsafe extern "C" fn(self_: *mut _cef_v8_context_t) -> c_int>

Returns true (1) if the underlying handle is valid and it can be accessed on the current thread. Do not call any other functions if this function returns false (0).

get_browser: Option<unsafe extern "C" fn(self_: *mut _cef_v8_context_t) -> *mut _cef_browser_t>

Returns the browser for this context. This function will return an NULL reference for WebWorker contexts.

get_frame: Option<unsafe extern "C" fn(self_: *mut _cef_v8_context_t) -> *mut _cef_frame_t>

Returns the frame for this context. This function will return an NULL reference for WebWorker contexts.

get_global: Option<unsafe extern "C" fn(self_: *mut _cef_v8_context_t) -> *mut _cef_v8_value_t>

Returns the global object for this context. The context must be entered before calling this function.

enter: Option<unsafe extern "C" fn(self_: *mut _cef_v8_context_t) -> c_int>

Enter this context. A context must be explicitly entered before creating a V8 Object, Array, Function or Date asynchronously. exit() must be called the same number of times as enter() before releasing this context. V8 objects belong to the context in which they are created. Returns true (1) if the scope was entered successfully.

exit: Option<unsafe extern "C" fn(self_: *mut _cef_v8_context_t) -> c_int>

Exit this context. Call this function only after calling enter(). Returns true (1) if the scope was exited successfully.

is_same: Option<unsafe extern "C" fn(self_: *mut _cef_v8_context_t, that: *mut _cef_v8_context_t) -> c_int>

Returns true (1) if this object is pointing to the same handle as |that| object.

eval: Option<unsafe extern "C" fn(self_: *mut _cef_v8_context_t, code: *const cef_string_t, script_url: *const cef_string_t, start_line: c_int, retval: *mut *mut _cef_v8_value_t, exception: *mut *mut _cef_v8_exception_t) -> c_int>

Execute a string of JavaScript code in this V8 context. The |script_url| parameter is the URL where the script in question can be found, if any. The |start_line| parameter is the base line number to use for error reporting. On success |retval| will be set to the return value, if any, and the function will return true (1). On failure |exception| will be set to the exception, if any, and the function will return false (0).
