Fields

base: cef_base_ref_counted_t

Base structure.

can_download: Option<unsafe extern "C" fn(self_: *mut _cef_download_handler_t, browser: *mut _cef_browser_t, url: *const cef_string_t, request_method: *const cef_string_t) -> c_int>

Called before a download begins in response to a user-initiated action (e.g. alt + link click or link click that returns a Content-Disposition: attachment response from the server). |url| is the target download URL and |request_function| is the target function (GET, POST, etc). Return true (1) to proceed with the download or false (0) to cancel the download.

on_before_download: Option<unsafe extern "C" fn(self_: *mut _cef_download_handler_t, browser: *mut _cef_browser_t, download_item: *mut _cef_download_item_t, suggested_name: *const cef_string_t, callback: *mut _cef_before_download_callback_t) -> c_int>

Called before a download begins. |suggested_name| is the suggested name for the download file. Return true (1) and execute |callback| either asynchronously or in this function to continue or cancel the download. Return false (0) to proceed with default handling (cancel with Alloy style, download shelf with Chrome style). Do not keep a reference to |download_item| outside of this function.

on_download_updated: Option<unsafe extern "C" fn(self_: *mut _cef_download_handler_t, browser: *mut _cef_browser_t, download_item: *mut _cef_download_item_t, callback: *mut _cef_download_item_callback_t)>

Called when a download’s status or progress information has been updated. This may be called multiple times before and after on_before_download(). Execute |callback| either asynchronously or in this function to cancel the download if desired. Do not keep a reference to |download_item| outside of this function.
