An error returned by credentials.

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.

Credential

Could not access a secure credential.

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.

Fields of Credential

name: String

The name of the credential we couldn't access.

cause: Box<Error>

The reason why we couldn't access it.

FileRead

Could not read file.

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.

Fields of FileRead

path: PathBuf

The file we couldn't access.

cause: Box<Error>

The reason why we couldn't access it.

InvalidUrl

We encountered an invalid URL.

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.

Fields of InvalidUrl

url: String

The invalid URL.

Io(Error)

An error occurred doing I/O.

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.

Json(Error)

We failed to parse JSON data.

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.

MissingEntry

Missing entry in Secretfile.

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.

Fields of MissingEntry

name: String

The name of the entry.

MissingKeyInPath

Path is missing a ':key' component.

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.

Fields of MissingKeyInPath

path: String

The invalid path.

MissingKeyInSecret

Secret does not have value for specified key.

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.

Fields of MissingKeyInSecret

secret: String

The name of the secret.

key: String

The key for which we have no value.

MissingVaultAddr

VAULT_ADDR not specified.

MissingVaultToken(Box<Error>)

Cannot get either VAULT_TOKEN or ~/.vault_token.

NoBackend

No credentials backend available.

NoHomeDirectory

Can't find home directory.

NonUnicodePath

Path cannot be represented as Unicode.

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.

Fields of NonUnicodePath

path: PathBuf

The path which cannot be represented as Unicode.

Parse

Parsing error.

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.

Fields of Parse

input: String

The input we couldn't parse.

Other(Box<dyn Error + Send + Sync + 'static>)

An unspecified kind of error occurred.

Secretfile(Box<Error>)

Can't read Secretfile.

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.

UndefinedEnvironmentVariable

Undefined environment variable.

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.

Fields of UndefinedEnvironmentVariable

name: String

The name of the environment variable.

cause: VarError

The error we encountered.

UnexpectedHttpStatus

Unexpected HTTP status.

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.

Fields of UnexpectedHttpStatus

status: StatusCode

The status we received.

body: String

The HTTP body we received.

UnparseableUrl(UrlError)

We failed to parse a URL.

Url

Fields of Url

url: Url

The URL we couldn't access.

cause: Box<Error>

The reason we couldn't access it.

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)>

The lower-level source of this error, if any.

fn backtrace(&self) -> Option<&Backtrace>

🔬 This is a nightly-only experimental API. (backtrace)

Returns a stack backtrace, if available, of where this error occurred.

fn description(&self) -> &str

👎 Deprecated since 1.42.0:

use the Display impl or to_string()

if let Err(e) = "xc".parse::<u32>() { // Print e itself, no need for description(). eprintln!("Error: {}", e); }

fn cause(&self) -> Option<&dyn Error>

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting
