Recorded entity declaration.

Fields

slot: Option<EntitySlot>

id: MetadataString

node_slot: Option<NodeSlot>

node_id: MetadataString

kind: EntityKind

source_name: MetadataString

source_name_kind: SourceNameKind

type_name: &'static str

type_hash: &'static str

qos: QoSProfile

callback_slot: Option<CallbackSlot>

callback_id: Option<MetadataString>

callback_source: SourceLocationMetadata

callback_group: Option<MetadataString>

action_cancel_callback_slot: Option<CallbackSlot>

action_cancel_callback_id: Option<MetadataString>

action_cancel_source: SourceLocationMetadata

action_accepted_callback_slot: Option<CallbackSlot>

action_accepted_callback_id: Option<MetadataString>

action_accepted_source: SourceLocationMetadata

period_ms: Option<u64>

period_us: Option<u64>

Issue #505 — the timer period at the executor’s own resolution. period_ms is kept (and still emitted) for consumers of the metadata JSON, but it truncates: a declared 33.333 ms timer used to reach the runtime as 33 ms, a 1% permanent rate error, and a sub-millisecond period reached it as zero.

parameter_type: Option<ParameterType>

parameter_default: Option<ParameterDefault>

parameter_read_only: bool

safety: bool

Phase 250 (Wave 2b) — a subscription that opted into E2E message-integrity validation (.safety()): the runtime registers it via create_generic_subscription_with_integrity and surfaces IntegrityStatus through CallbackCtx::integrity(). Ungated (a plain flag) — only the runtime branch that reads it is gated on safety-e2e, so when the capability is off the flag is simply ignored (the subscription registers as a basic one). false for every other entity.

Trait Implementations

impl Clone for EntityMetadata

fn clone(&self) -> EntityMetadata

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for EntityMetadata

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for EntityMetadata

impl PartialEq for EntityMetadata

fn eq(&self, other: &EntityMetadata) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
