Failure modes of a pipeline edit. Distinct from the entity-centric crate::engine::EngineError — these describe four-primitive store edits. key is the display identity: "<mem>/<name>".

Variants

NoWorkspaceRoot

The engine was not booted from a workspace root, so there is no four-primitive store to edit (e.g. an engine built from a bare mount list in a test or in-memory consumer).

AlreadyExists

A create targeted a (mem, name) that already holds a record.

Fields

primitive: &'static str

key: String

NotFound

An update / delete / rename targeted a record that does not exist.

Fields

primitive: &'static str

key: String

Referenced

A delete was refused because other records still reference the target.

Fields

primitive: &'static str

key: String

referrers: Vec<String>

RenameTargetExists

A rename target (mem, new) already holds a record.

Fields

primitive: &'static str

key: String

InvalidJson

A JSON-string edit entry point received a payload that did not deserialize into the target primitive.

Fields

primitive: &'static str

message: String

Store(StoreError)

Underlying store IO / parse failure.

Trait Implementations

impl Debug for PipelineEditError

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

Formats the value using the given formatter.

impl Display for PipelineEditError

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

Formats the value using the given formatter.

impl Error for PipelineEditError

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<StoreError> for PipelineEditError

fn from(source: StoreError) -> Self

Converts to this type from the input type.
