Enum WriteError

Available on crate feature writer only.

Why the writer refused a catalog (plans/02-catalog-format.md §2.9).

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.

Nul(String)

A string contains U+0000, which has no syntax form and no catalog form.

UnknownVariable

A variable is neither a local in scope nor in the message’s slot list.

Fields

message: usize

The message’s index (its MsgId index).

name: String

The variable’s name as written.

UnknownFunction

A function is not in the manifest’s function set.

Fields

message: usize

The message’s index.

name: String

The function’s identifier as written.

InputName

An .input declaration whose name differs from its variable’s.

Fields

message: usize

The message’s index.

name: String

The declaration’s name.

variable: String

Its variable’s name.

Unsupported

A data-model node this format version cannot represent.

Fields

message: usize

The message’s index.

Manifest(&'static str)

The manifest and the messages do not fit together, or the manifest’s lists are not strictly ascending.

Dir

The header direction must be ltr or rtl.

LocaleEntry(u32)

A LOCALE entry is duplicated or malformed.

Fallback(&'static str)

A fallback entry names a message twice or out of range, or there are more than 256 fallback locales.

TooLarge(&'static str)

Beyond the format’s limits (2²⁴ messages, 2³⁰ bytes of MESSAGES or STRINGS, 2³² for counts).

Internal(&'static str)

A writer bug: the two passes disagreed.

Trait Implementations

impl Clone for WriteError

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 WriteError

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

Formats the value using the given formatter.

impl Display for WriteError

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

Formats the value using the given formatter.

impl Eq for WriteError

impl Error for WriteError

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 WriteError

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

Equality operator ==.

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

Inequality operator !=.
