Why a tabular record was refused.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

RaggedRow

A row carries a different cell count than the first row (WR1).

Ragged tables parse and render; the damage appears only when a reader indexes a column the short row does not have.

Fields

entity: &'static str

The entity being staged.

row: usize

Zero-based index of the offending row.

expected: usize

Cells in the first row.

found: usize

Cells in this row.

TooManyHeadings

More than one row is marked as a heading (WR2).

Fields

entity: &'static str

The entity being staged.

found: usize

How many rows claimed to be headings.

EmptyList

A required list was empty.

The schema spells these LIST [1:?], so an empty list is not a sparse record but a malformed one.

Fields

entity: &'static str

The entity being staged.

attribute: &'static str

The attribute that came up empty.

BlankRequired

A required label was absent or whitespace-only.

A blank string satisfies EXISTS while naming nothing, so it is refused rather than written.

Fields

entity: &'static str

The entity being staged.

attribute: &'static str

The attribute that was blank.

NotFinite

A numeric attribute was not finite.

Fields

entity: &'static str

The entity being staged.

attribute: &'static str

The offending attribute.

Trait Implementations

impl Clone for TabularError

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 TabularError

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

Formats the value using the given formatter.

impl Display for TabularError

impl Eq for TabularError

impl Error for TabularError

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 TabularError

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

Equality operator ==.

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

Inequality operator !=.
