Workflow / chain failure (stderr via wyvern_schema::ErrorCode::WorkflowError).

Variants

PathDenied

Path escaped {wyvern_share}, cwd, or the current wizard directory.

Fields

path: PathBuf

Offending path after expansion.

Timeout

Script exceeded 30s.

Fields

stderr_tail: String

Last 4 KiB of child stderr collected before kill.

NonZero

Script exit status was not zero.

Fields

status: i32

Process exit code (or 1 when killed by signal).

stderr_tail: String

Last 4 KiB of child stderr.

InvalidStdout

Pre stdout was not one JSON object with an object config_patch.

Fields

cause: String

Parse / shape failure detail.

ChainDepth

A 17th hop was requested.

Fields

max: u32

Configured maximum (16).

Resolve

{wyvern_share} / relative path could not be resolved.

Fields

path: String

Original path string.

cause: String

Why resolution failed.

MissingPython3

.py script and python3 is not on PATH.

Merge

input or config_patch was not a JSON object.

Fields

cause: String

Merge failure detail.

Implementations

impl WorkflowError

pub fn recovery(&self) -> Vec<String>

Stable recovery steps for stderr JSON (RBP-001).

pub fn cause(&self) -> String

Short cause string for the stderr envelope.

pub fn subcode(&self) -> &'static str

Stable sub-discriminator for machine branching under WORKFLOW_ERROR.

Trait Implementations

impl Debug for WorkflowError

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

Formats the value using the given formatter.

impl Display for WorkflowError

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

Formats the value using the given formatter.

impl Error for WorkflowError

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.
