Struct _cef_preference_registrar_t 

#[repr(C)]
pub struct _cef_preference_registrar_t {
    pub base: cef_base_scoped_t,
    pub add_preference: Option<unsafe extern "C" fn(self_: *mut _cef_preference_registrar_t, name: *const cef_string_t, default_value: *mut _cef_value_t) -> c_int>,
}

Structure that manages custom preference registrations.

NOTE: This struct is allocated DLL-side.

Fields

base: cef_base_scoped_t

Base structure.

add_preference: Option<unsafe extern "C" fn(self_: *mut _cef_preference_registrar_t, name: *const cef_string_t, default_value: *mut _cef_value_t) -> c_int>

Register a preference with the specified |name| and |default_value|. To avoid conflicts with built-in preferences the |name| value should contain an application-specific prefix followed by a period (e.g. “myapp.value”). The contents of |default_value| will be copied. The data type for the preference will be inferred from |default_value|’s type and cannot be changed after registration. Returns true (1) on success. Returns false (0) if |name| is already registered or if |default_value| has an invalid type. This function must be called from within the scope of the cef_browser_process_handler_t::OnRegisterCustomPreferences callback.
