Struct lv2_sys::_LV2UI_Port_Map

#[repr(C)]
pub struct _LV2UI_Port_Map {
    pub handle: LV2UI_Feature_Handle,
    pub port_index: Option<unsafe extern "C" fn(handle: LV2UI_Feature_Handle, symbol: *const c_char) -> u32>,
}

Feature to map port symbols to UIs.

This can be used by the UI to get the index for a port with the given symbol. This makes it possible to implement and distribute a UI separately from the plugin (since symbol, unlike index, is a stable port identifier).

Fields

handle: LV2UI_Feature_Handle

Pointer to opaque data which must be passed to port_index().

port_index: Option<unsafe extern "C" fn(handle: LV2UI_Feature_Handle, symbol: *const c_char) -> u32>

Get the index for the port with the given symbol.

@return The index of the port, or LV2UI_INVALID_PORT_INDEX if no such port is found.
