Enum NodeDeclError 

pub enum NodeDeclError {
    Metadata(NodeMetadataError),
    MissingExport,
    Runtime,
    ExecutorFull,
    UnknownPublisher,
}

Node declaration error.

Variants

Metadata(NodeMetadataError)

Metadata recorder rejected the declaration.

MissingExport

Host/runtime discovery could not find nros::node! export.

Runtime

Generated runtime rejected the declaration.

ExecutorFull

The executor’s fixed callback-entry table is full — a timer / subscription / service / action could not claim a slot (issue 0095). Carries the capacity cause through the NodeError → NodeDeclError collapse so the register seam can name NROS_EXECUTOR_MAX_CBS.

UnknownPublisher

A publish named an entity this component has no publisher for — the LOOKUP failed, nothing was ever handed to the transport.

issue 0736 — split out of Self::Runtime, which the publish path returned for BOTH “the transport rejected the sample” and “there is no such publisher”: lookup_publisher(...).unwrap_or(Err(Runtime)). Those are different bugs in different layers with different fixes, and from a serial console they were the same line. Exactly the conflation #572 removed one level out, where discarding the result made “the timer never fired” and “every publish failed” the same observation.

Implementations

impl NodeDeclError

pub const fn message(self) -> &'static str

Human-readable static message for diagnostics that cross FFI/plugin boundaries.

Trait Implementations

impl Clone for NodeDeclError

fn clone(&self) -> NodeDeclError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for NodeDeclError

impl Debug for NodeDeclError

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

Formats the value using the given formatter.

impl Eq for NodeDeclError

impl From<NodeDeclError> for ExecutorError

fn from(e: NodeDeclError) -> Self

Converts to this type from the input type.

impl From<NodeMetadataError> for NodeDeclError

fn from(value: NodeMetadataError) -> Self

Converts to this type from the input type.

impl PartialEq for NodeDeclError

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