[−][src]Struct lv2_sys::_LV2_Options_Option
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.
Fields
context: LV2_Options_Context

key: LV2_URID
< Key (property).
size: u32
< Size of value in bytes.
type_: LV2_URID
< Type of value (datatype).
value: *const c_void
< Pointer to value (object).
