What stops a 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.

Io

A file could not be read or written.

Fields

path: PathBuf

The file.

source: Error

What the operating system said.

Config

mf2.toml is not valid TOML, or a key in it is wrong.

Fields

path: PathBuf

The configuration file.

message: String

Which key, and what is wrong with it.

Json

A flat JSON corpus is not an object of strings.

Fields

path: PathBuf

The file.

line: u32

One-based line.

column: u32

One-based column.

message: String

What is wrong.

Locale

The locale directory names a tag the catalog format cannot write.

Fields

locale: String

The tag.

source: Error

What the locale data said.

Write

The catalog writer refused a locale’s messages.

Fields

locale: String

The tag.

source: WriteError

What the writer said.

LocaleData(Error)

The locale data could not be sliced.

Manifest(ManifestError)

The manifest could not be written or read back.

Catalog(WriteError)

A catalog could not be written.

Compress

A catalog could not be compressed.

Both encoders write into a Vec, so this is a compressor fault, not a full disk. It is still an error rather than a shrug: a truncated .br would be served immutable beside a .mf2b whose content hash says it is intact, and the client would see a corrupt catalog.

Fields

locale: String

The tag.

format: &'static str

brotli or gzip.

source: Error

What the encoder said.

Layout(String)

The layout on disk is not what a build needs.

LocaleVariant

Two locales’ tags give the generated Locale one variant: pt-BR and pt_br are both Locale::PtBr.

Fields

first: String

The first of the two tags.

second: String

The second.

variant: String

The variant they share.

MarkupHash

Two markup names have one hash, so a style could not tell them apart.

Fields

first: String

The first of the two.

second: String

The second.

Corpus

The build found errors in the corpus; they are in the report.

Fields

errors: usize

How many errors.

locales: usize

In how many locales.

NoMf2

run cannot see mf2’s features: cargo passes them only to a crate that names mf2 as a normal dependency.

Mf2Version

mf2 and mf2-build are not the same version.

Fields

mf2: String

What mf2 says its version is.

build: String

This crate’s.

IcuBlob

mf2 has datetime-icu, and this mf2-build was built without icu-blob, which writes ICU4X’s date data into the catalogs. A build-dependency’s features cannot come through links.

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<Error> for Error

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<ManifestError> for Error

fn from(source: ManifestError) -> 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.
