Why a document could not be written or read.

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.

Json(String)

The text is not JSON.

NotADesign

The JSON is not a document of this format: its format is missing or another.

Fields

found: String

What the document holds, as JSON, or missing.

Unsupported

The document is of a version this reader neither takes nor migrates from.

Fields

found: Version

The document’s version.

supported: Version

The version this reader takes and writes.

Invalid(String)

The document names the format and version but does not follow the schema.

NotRepresentable(String)

The design holds a value JSON cannot carry exactly, such as a number that is not finite, so the text would not read back as the same design.

Ork(String)

The .ork could not be written.

Container(String)

A .hprz container could not be read or written (container).

Trait Implementations

impl Clone for FormatError

fn clone(&self) -> FormatError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FormatError

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

Formats the value using the given formatter.

impl Display for FormatError

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

Formats the value using the given formatter.

impl Error for FormatError

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 FormatError

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
