Enum StepError 

pub enum StepError {
    CellMismatch(Vec<CellDiff>),
    DocStringMismatch(DocStringDiff),
    ReturnShape(String),
    UnexpectedPass,
    Handler(HandlerError),
}

A step failure verdict — the closed union replacing the exception hierarchy.

Variants

CellMismatch(Vec<CellDiff>)

Table / header-bound row mismatch (only the failing cells).

DocStringMismatch(DocStringDiff)

Doc-string body mismatch.

ReturnShape(String)

Wrong return type/shape — an author mistake, not a value diff.

UnexpectedPass

An error-fenced example ran without failing.

Handler(HandlerError)

An author-signalled failure (Err) or a caught panic.

Implementations

impl StepError

pub fn message(&self) -> String

The human-readable message (getMessage() parity).

pub fn as_cell_mismatch(&self) -> Option<&[CellDiff]>

The failing cells of a StepError::CellMismatch, else None (isCellMismatchException parity).

pub fn as_doc_string_mismatch(&self) -> Option<&DocStringDiff>

The diff of a StepError::DocStringMismatch, else None.
