A problem with the shipped rule table or the CLDR input.

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.

Parse(ParseError)

A plural rule does not parse.

Rule

A plural rule of the shipped table does not parse.

Fields

kind: &'static str

cardinal or ordinal.

locale: String

The locale.

category: String

The plural category.

source: ParseError

Why.

Table

A line of a shipped table is malformed.

Fields

line: usize

One-based line.

message: String

What is wrong.

Pattern

A CLDR number pattern the encoder does not accept.

Fields

pattern: String

The pattern.

message: &'static str

What is wrong.

Missing

A locale’s number data lacks a field.

Fields

locale: String

The locale.

system: String

The numbering system.

field: &'static str

The missing field.

Entry(WriteError)

The catalog writer refused a LOCALE entry.

Json(Error)

Available on crate feature extract only.

The CLDR JSON does not parse (extract).

Shape(String)

Available on crate feature extract only.

The CLDR JSON is not shaped as expected (extract).

Assumption(String)

Available on crate feature extract only.

The CLDR input breaks an assumption the table format rests on (the extractor checks each one, so a CLDR update that changes them is noticed, not silently mis-encoded).

Io

Available on crate feature extract only.

A file could not be read or written (extract).

Fields

path: PathBuf

The file.

source: Error

What the operating system said.

IcuData(DataError)

Available on crate feature icu-blob only.

ICU4X data for icu.blob (icu-blob).

IcuBlobBuild

Available on crate feature icu-blob only.

Some formatter of the datetime-icu backend does not build from ICU4X’s data for the locale (icu-blob).

Fields

locale: String

The locale.

count: usize

How many formatters fail.

first: String

The first that does.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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 From<DataError> for Error

fn from(source: DataError) -> Self

Converts to this type from the input type.

impl From<Error> for Error

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<ParseError> for Error

fn from(source: ParseError) -> Self

Converts to this type from the input type.

impl From<WriteError> for Error

fn from(source: WriteError) -> Self

Converts to this type from the input type.
