/**
 * An event for passthrough state changes.
 * 
 * Member Descriptions
 * 
 * 
 * {@code type} is the {@code XrStructureType} of this structure.
 * {@code next} is {@code NULL} or a pointer to the next structure in a structure chain. No such structures are defined in core OpenXR or this extension.
 * {@code flags} {@code XrPassthroughStateChangedFlagsFB} that specify additional behavior.
 * 
 * 
 * Valid Usage (Implicit)
 * 
 * 
 * The {@link FBPassthrough XR_FB_passthrough} extension must be enabled prior to using {@link XrEventDataPassthroughStateChangedFB}
 * {@code type} must be {@link FBPassthrough#XR_TYPE_EVENT_DATA_PASSTHROUGH_STATE_CHANGED_FB TYPE_EVENT_DATA_PASSTHROUGH_STATE_CHANGED_FB}
 * {@code next} must be {@code NULL} or a valid pointer to the next structure in a structure chain
 * {@code flags} must be a valid combination of {@code XrPassthroughStateChangedFlagBitsFB} values
 * {@code flags} must not be 0
 * 
 * 
 * Layout
 * 
 * 
 * struct XrEventDataPassthroughStateChangedFB {
