A BigML-related error.

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.

CouldNotAccessUrl

Fields

Non-exhaustive enum variants could have additional fields added in future. Therefore, non-exhaustive enum variants cannot be constructed in external crates and cannot be matched against.

url: Url

source: Box<Error>

We could not access the specified URL.

WARNING: Do not construct this directly, but use Error::could_not_access_url to handle various URL sanitization and security issues.

CouldNotGetOutput

Fields

Non-exhaustive enum variants could have additional fields added in future. Therefore, non-exhaustive enum variants cannot be constructed in external crates and cannot be matched against.

name: String

source: Box<Error>

We could not get an output value from a WhizzML script.

CouldNotParseUrlWithDomain

Fields

Non-exhaustive enum variants could have additional fields added in future. Therefore, non-exhaustive enum variants cannot be constructed in external crates and cannot be matched against.

domain: String

source: Box<ParseError>

We could not parse the specified URL.

WARNING: This takes a domain, not the full URL that we couldn’t parse, because we want to be careful to exclude credentials from error messages, and we can’t remove credentials from a URL we can’t parse.

CouldNotReadFile

Fields

Non-exhaustive enum variants could have additional fields added in future. Therefore, non-exhaustive enum variants cannot be constructed in external crates and cannot be matched against.

path: PathBuf

source: Box<Error>

We could not read a file.

MissingEnvVar

Fields

Non-exhaustive enum variants could have additional fields added in future. Therefore, non-exhaustive enum variants cannot be constructed in external crates and cannot be matched against.

var: String

The user must specify the environment variable var.

OutputNotAvailable

Fields

Non-exhaustive enum variants could have additional fields added in future. Therefore, non-exhaustive enum variants cannot be constructed in external crates and cannot be matched against.

We could not access an output value of a WhizzML script.

PaymentRequired

Fields

Non-exhaustive enum variants could have additional fields added in future. Therefore, non-exhaustive enum variants cannot be constructed in external crates and cannot be matched against.

url: Url

body: String

BigML says that payment is required for this request, perhaps because we have hit plan limits.

Timeout

Fields

Non-exhaustive enum variants could have additional fields added in future. Therefore, non-exhaustive enum variants cannot be constructed in external crates and cannot be matched against.

A request timed out.

UnexpectedHttpStatus

Fields

Non-exhaustive enum variants could have additional fields added in future. Therefore, non-exhaustive enum variants cannot be constructed in external crates and cannot be matched against.

url: Url

status: StatusCode

body: String

We received an unexpected HTTP status code.

UnknownBigMlType

Fields

Non-exhaustive enum variants could have additional fields added in future. Therefore, non-exhaustive enum variants cannot be constructed in external crates and cannot be matched against.

type_name: String

We encountered an unknown BigML value type.

WaitFailed

Fields

Non-exhaustive enum variants could have additional fields added in future. Therefore, non-exhaustive enum variants cannot be constructed in external crates and cannot be matched against.

id: String

The ID of the resource that we were waiting on.

message: String

The message that was returned.

We tried to create a BigML resource, but we failed. Display a dashboard URL to make it easy to look up the actual error.

WrongResourceType

Fields

Non-exhaustive enum variants could have additional fields added in future. Therefore, non-exhaustive enum variants cannot be constructed in external crates and cannot be matched against.

expected: &'static str

found: String

We found a type mismatch deserializing a BigML resource ID.

Other

Fields

Non-exhaustive enum variants could have additional fields added in future. Therefore, non-exhaustive enum variants cannot be constructed in external crates and cannot be matched against.

source: Box<dyn StdError + Send + Sync + 'static>

The original error.

We add Send + Sync to make it easy to use in the presence of threads, and 'static to make sure it depends on no borrowed data.

Another kind of error occurred.
