Why FluentZeroBuilder::try_generate failed.

FluentZeroBuilder::generate panics with this error’s Display text, prefixed with fluent-zero-build: .

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.

MissingOutDir

The OUT_DIR environment variable is not set, i.e. the builder is not running inside a Cargo build script.

InvalidCratePath(String)

The path given to FluentZeroBuilder::crate_path is not a Rust path.

InvalidFallbackLocale

The locale given to FluentZeroBuilder::fallback_locale is not a valid language identifier.

Fields

locale: String

The locale as configured.

reason: String

Why it does not parse.

MissingFallbackLocale

The locales directory holds locales, but none of them is the configured fallback locale.

Fields

locale: String

The configured fallback locale, in canonical form.

locales_dir: PathBuf

The locales directory that was searched.

available: Vec<String>

The locales that do exist, sorted.

Io

Reading a locale file or writing generated output failed.

Fields

path: PathBuf

The file or directory being read or written.

source: Error

The underlying error.

DuplicateId

A message or term ID is defined more than once within one locale.

Fields

id: String

The ID as written (terms keep their - prefix).

lang: String

The locale, e.g. en-US.

first: (PathBuf, usize)

File and 1-based line of the first definition.

second: (PathBuf, usize)

File and 1-based line of the repeated definition.

Parse

An .ftl file contains syntax errors.

Fields

path: PathBuf

The offending file.

message: String

Every error in the file, each as path:line:col: error followed by the offending source line and a caret under the error position.

MissingTranslations

Translations are missing under MissingTranslations::Deny.

Fields

report: Vec<String>

One line per incomplete locale, sorted by locale: how many messages of the fallback locale it lacks and the first few IDs.

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, f: &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>)
