Errors that can occur while getting an access token from an ExternallyManagedCredential.

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.

Spawn

The program could not be started.

Fields

program: PathBuf

The program that could not be started.

source: Error

The underlying error.

Read

The program’s output could not be read.

Fields

program: PathBuf

The program whose output could not be read.

source: Error

The underlying error.

Timeout

The program did not finish within its timeout and was killed.

Fields

program: PathBuf

The program that timed out.

timeout: Duration

The timeout that elapsed.

ExitStatus

The program exited unsuccessfully.

Fields

program: PathBuf

The program that failed.

status: String

The exit status it reported.

stderr: String

What it wrote to stderr, truncated.

OutputTooLarge

The program wrote more to stdout than an access token could plausibly need.

Fields

program: PathBuf

The program that wrote too much.

limit: usize

The limit it exceeded.

InvalidUtf8

The program’s output was not valid UTF-8.

Fields

program: PathBuf

The program with invalid output.

EmptyOutput

The program wrote nothing to stdout.

Fields

program: PathBuf

The program that wrote nothing.

Trait Implementations

impl Debug for ExternalCommandError

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

Formats the value using the given formatter.

impl Display for ExternalCommandError

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

Formats the value using the given formatter.

impl Error for ExternalCommandError

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.
