Error types for patch operations.

Marked #[non_exhaustive]: downstream match expressions must include a wildcard arm, so new variants can be added in future without breaking callers.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

InvalidNode

A referenced node does not exist in the patch.

Fields

node: NodeId

InvalidPort

A referenced port does not exist on the given node.

Carries enough context to be actionable: the offending node, the requested port by name and/or id (whichever the caller supplied), and the list of valid port names on that node so the message can suggest the intended target.

Fields

node: NodeId

name: Option<String>

port: Option<PortId>

available: Vec<String>

InvalidCable

CycleDetected

A feedback cycle with no cycle-breaker (delay) was detected.

nodes are the NodeIds stuck in the cycle; names are their resolved module names captured at error-construction time so Display can print the actual path without a back-reference to the Patch.

Fields

nodes: Vec<NodeId>

names: Vec<String>

CompilationFailed(String)

SignalMismatch

Signal type mismatch (only in Strict validation mode)

Fields

from_kind: SignalKind

to_kind: SignalKind

message: String

Trait Implementations

impl Clone for PatchError

fn clone(&self) -> PatchError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PatchError

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

Formats the value using the given formatter.

impl Display for PatchError

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

Formats the value using the given formatter.

impl Error for PatchError

Available on crate feature std only.

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl From<PatchError> for QuiverError

Available on crate feature wasm only.

fn from(e: PatchError) -> Self

Converts to this type from the input type.
