Struct lv2_sys::_LV2_Options_Option

#[repr(C)]pub struct _LV2_Options_Option {
    pub context: LV2_Options_Context,
    pub subject: u32,
    pub key: LV2_URID,
    pub size: u32,
    pub type_: LV2_URID,
    pub value: *const c_void,
}

An option.

This is a property with a subject, also known as a triple or statement.

This struct is useful anywhere a statement needs to be passed where no memory ownership issues are present (since the value is a const pointer).

Options can be passed to an instance via the feature LV2_OPTIONS__options with data pointed to an array of options terminated by a zeroed option, or accessed/manipulated using LV2_Options_Interface.
