Fields

base: _cef_base_ref_counted_t

Base structure.

can_download: Option<unsafe extern "C" fn(*mut _cef_download_handler_t, *mut _cef_browser_t, *const _cef_string_utf16_t, *const _cef_string_utf16_t) -> i32>

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(*mut _cef_download_handler_t, *mut _cef_browser_t, *mut _cef_download_item_t, *const _cef_string_utf16_t, *mut _cef_before_download_callback_t)>

Called before a download begins. |suggested_name| is the suggested name for the download file. By default the download will be canceled. Execute |callback| either asynchronously or in this function to continue the download if desired. Do not keep a reference to |download_item| outside of this function.

on_download_updated: Option<unsafe extern "C" fn(*mut _cef_download_handler_t, *mut _cef_browser_t, *mut _cef_download_item_t, *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.
