Enum NodeError 

pub enum NodeError {
    Transport(TransportError),
    NameTooLong,
    Serialization,
    Deserialization,
    BufferTooSmall,
    ActionCreationFailed,
    ServiceRequestFailed,
    ServiceReplyFailed,
    Timeout,

}

Error type for generic embedded node operations.

Not Copy — NodeError::Transport wraps a TransportError which carries owned diagnostic strings (Backend / BackendDynamic). Rust callers that matched on NodeError by value may need ref arms or .clone(); C/C++ callers are unaffected (they see an integer nros_ret_t).

Variants

Transport(TransportError)

Transport-level error.

NameTooLong

Node name exceeds 64 bytes.

Serialization

CDR serialization failed.

Deserialization

CDR deserialization failed.

BufferTooSmall

Buffer too small for message.

ActionCreationFailed

Action server/client creation failed.

ServiceRequestFailed

Service request failed.

ServiceReplyFailed

Service reply failed.

Timeout

Operation timed out.

NotInitialized

A required subsystem has not been initialized (e.g. parameter services have not been registered on the executor).

RequestInFlight

The client / action client already has a request in flight that hasn’t been consumed. Phase 84.D3: fixes the hazard where dropping a Promise without awaiting its reply left the stale reply queued to be delivered to the next call. Resolve by either polling the existing promise to completion or calling reset_in_flight().

NoSchedContextSlot

Phase 110.B — create_sched_context ran out of slots (MAX_SC exceeded).

InvalidSchedContextBinding

Phase 110.B — bind_handle_to_sched_context was called with an out-of-range handle, an empty entry slot, or an unknown SchedContextId.

NodeTableFull

Phase 104.C.2 — Executor::node_builder(...).build() was called when the per-Executor node table is full (NROS_EXECUTOR_MAX_NODES reached).

BackendMismatch

Phase 104.C.2 — requested RMW backend does not match the Executor’s open session (single-session restriction lifts in Phase 104.C.3 when the per-Node session cache lands).

Trait Implementations

impl Clone for NodeError

fn clone(&self) -> NodeError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NodeError

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

Formats the value using the given formatter.

impl From<DeserError> for NodeError

fn from(_: DeserError) -> Self

Converts to this type from the input type.

impl From<SerError> for NodeError

fn from(_: SerError) -> Self

Converts to this type from the input type.

impl From<TransportError> for NodeError

fn from(err: TransportError) -> Self

Converts to this type from the input type.

impl PartialEq for NodeError

fn eq(&self, other: &NodeError) -> 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.
