Errors that can occur during patch operations.

Variants

NodeNotFound

The patch targets a node ID that doesn’t exist in the module.

Fields

node_id: String

The node ID that was not found.

FunctionNotFound

The patch targets a function ID that doesn’t exist.

Fields

func_id: String

The function ID that was not found.

DuplicateFunction

Adding a function with a name that already exists in the module.

Fields

name: String

The duplicate name.

ValidationFailed

Structural validation of one of the patch operations failed.

Fields

op_index: usize

Index into Patch::operations where validation failed.

message: String

Validation error message.

TypeCheckFailed

The module produced by the patch fails type checking.

Fields

message: String

Summary of type errors.

VersionMismatch

The patch was written against a different module version than the current state.

Fields

expected: String

The version the patch was written against.

actual: String

The actual current module version.

Trait Implementations

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, __formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for PatchError

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.
