Implement this structure to handle events related to browser load status. The functions of this structure will be called on the browser process UI thread or render process main thread (TID_RENDERER).

NOTE: This struct is allocated client-side.

Fields

base: cef_base_ref_counted_t

Base structure.

on_loading_state_change: Option<unsafe extern "C" fn(self_: *mut _cef_load_handler_t, browser: *mut _cef_browser_t, isLoading: c_int, canGoBack: c_int, canGoForward: c_int)>

Called when the loading state has changed. This callback will be executed twice – once when loading is initiated either programmatically or by user action, and once when loading is terminated due to completion, cancellation of failure. It will be called before any calls to OnLoadStart and after all calls to OnLoadError and/or OnLoadEnd.

on_load_start: Option<unsafe extern "C" fn(self_: *mut _cef_load_handler_t, browser: *mut _cef_browser_t, frame: *mut _cef_frame_t, transition_type: cef_transition_type_t)>

Called after a navigation has been committed and before the browser begins loading contents in the frame. The |frame| value will never be NULL – call the is_main() function to check if this frame is the main frame. |transition_type| provides information about the source of the navigation and an accurate value is only available in the browser process. Multiple frames may be loading at the same time. Sub-frames may start or continue loading after the main frame load has ended. This function will not be called for same page navigations (fragments, history state, etc.) or for navigations that fail or are canceled before commit. For notification of overall browser load status use OnLoadingStateChange instead.

on_load_end: Option<unsafe extern "C" fn(self_: *mut _cef_load_handler_t, browser: *mut _cef_browser_t, frame: *mut _cef_frame_t, httpStatusCode: c_int)>

Called when the browser is done loading a frame. The |frame| value will never be NULL – call the is_main() function to check if this frame is the main frame. Multiple frames may be loading at the same time. Sub-frames may start or continue loading after the main frame load has ended. This function will not be called for same page navigations (fragments, history state, etc.) or for navigations that fail or are canceled before commit. For notification of overall browser load status use OnLoadingStateChange instead.

on_load_error: Option<unsafe extern "C" fn(self_: *mut _cef_load_handler_t, browser: *mut _cef_browser_t, frame: *mut _cef_frame_t, errorCode: cef_errorcode_t, errorText: *const cef_string_t, failedUrl: *const cef_string_t)>

Called when a navigation fails or is canceled. This function may be called by itself if before commit or in combination with OnLoadStart/OnLoadEnd if after commit. |errorCode| is the error code number, |errorText| is the error text and |failedUrl| is the URL that failed to load. See net\base\net_error_list.h for complete descriptions of the error codes.
