Failure deriving an OutputPlan — the output-side mirror of the loader seam’s errors. Every variant names the offending variable or dimension: a mislabeled axis is silently wrong science, so these fail loudly.

Variants

DuplicateScalar

A scalar (bracket-free) cell key appeared more than once.

Fields

base: String

count: usize

RaggedRank

Cells of one variable disagreed on how many axes the variable has.

Fields

base: String

got: usize

expected: usize

ZeroIndex

A cell key carried a 0 (or negative) index; cell keys are 1-based.

Fields

base: String

axis: usize

SparseGrid

The variable’s cells do not cover its grid.

Fields

base: String

shape: Vec<usize>

got: usize

want: usize

DuplicateCell

Two flat slots claimed the same grid cell.

Fields

base: String

cell: Vec<usize>

DimCountMismatch

The document’s declared shape has a different rank than the flat state.

Fields

base: String

dims: Vec<String>

declared: usize

shape: Vec<usize>

actual: usize

DimLengthMismatch

A declared index set’s length disagrees with the recovered axis length.

Fields

base: String

axis: usize

dim: String

size: usize

len: usize

DimLengthConflict

Two variables on one grid disagree about a shared dimension’s length.

Fields

dim: String

first: String

a: usize

second: String

b: usize

TimeDimCollision

A spatial dimension collides with the record (time) axis name.

Fields

base: String

dim: String

CoordLengthMismatch

A coordinates entry’s inline values length does not match its axis.

Fields

name: String

got: usize

want: usize

UnknownObserved

The caller asked for an observed field that has no slot in the flat state. Silently dropping a requested output is worse than refusing.

Fields

name: String

AmbiguousRequest

A requested output names no variable exactly, and its last dotted segment is shared by more than one variable, so it designates none of them (CONFORMANCE_SPEC §5.17.4). Code ambiguous_output_name.

Fields

name: String

candidates: Vec<String>

BufferLength

A scatter/gather call was handed a buffer of the wrong length.

Fields

base: String

what: &'static str

got: usize

want: usize

Implementations

impl OutputError

pub fn code(&self) -> Option<&'static str>

The registered diagnostic code (a value of crate::ERROR_CODES) for the variants that carry one.

Trait Implementations

impl Clone for OutputError

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for OutputError

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

Formats the value using the given formatter.

impl Display for OutputError

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

Formats the value using the given formatter.

impl Eq for OutputError

impl Error for OutputError

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 PartialEq for OutputError

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
