Struct RestartFlags 

pub struct RestartFlags(/* private fields */);

What a plugin asked the host to re-read, reported through IComponentHandler::restartComponent and drained with Plugin::take_restart_flags.

A plugin raises these when something about it changed behind the host’s back — a preset load that renamed its parameters, a mode switch that changed its latency, an oversampling toggle that changed its bus layout. Poll this alongside Plugin::take_parameter_edits and respond directly, or use Plugin::service_host_requests for lifecycle-sensitive changes:

• param_values_changed — re-read values with Plugin::get_parameters.
• param_titles_changed — re-read the parameter list itself (ids, names, ranges may all differ).
• latency_changed — re-read Plugin::latency_samples and adjust delay compensation. Requires stopping processing first, per the VST3 spec.
• io_changed — the bus layout changed; re-query Plugin::bus_arrangements and reconfigure. Nothing is rebuilt for you.

Implementations

impl RestartFlags

pub fn bits(self) -> i32

The raw VST3 bitmask (Steinberg::Vst::RestartFlags), for flags this type doesn’t name.

pub fn is_empty(self) -> bool

True when the plugin raised no flags since the last drain.

pub fn param_values_changed(self) -> bool

kParamValuesChanged: parameter values changed (e.g. a preset was loaded).

pub fn reload_component(self) -> bool

kReloadComponent: the component must be recreated by the outer host.

pub fn param_titles_changed(self) -> bool

kParamTitlesChanged: the parameter list itself changed (ids, names, ranges, count).

pub fn latency_changed(self) -> bool

kLatencyChanged: the plugin’s reported latency changed.

pub fn io_changed(self) -> bool

kIoChanged: the plugin’s bus configuration changed.

pub fn midi_cc_assignment_changed(self) -> bool

kMidiCCAssignmentChanged: controller-to-parameter mappings changed.

pub fn note_expression_changed(self) -> bool

kNoteExpressionChanged: note-expression metadata changed.

pub fn io_titles_changed(self) -> bool

kIoTitlesChanged: bus names changed.

pub fn prefetchable_support_changed(self) -> bool

kPrefetchableSupportChanged: prefetch support changed.

pub fn routing_info_changed(self) -> bool

kRoutingInfoChanged: routing metadata changed.

pub fn keyswitch_changed(self) -> bool

kKeyswitchChanged: keyswitch metadata changed.

pub fn param_id_mapping_changed(self) -> bool

kParamIDMappingChanged: processor/controller parameter-id mappings changed.
