Enum TokenSourceError 

#[non_exhaustive]
pub enum TokenSourceError {
    Exec,
    Invalid,
    Timeout,
    Other,
}

Failure classes a TokenSource may report.

Every variant is fully redacted: neither Debug nor std::fmt::Display reveals any inner detail. The variants carry no payload by construction, so a token, a signed assertion, or a raw provider response can never leak through a token-source failure into logs, error chains, or panic output. A provider maps its underlying error into one of these classes and drops the detail — fail-closed.

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.

Exec

The provider (command / process / HTTP call) failed to execute or exited unsuccessfully.

Invalid

The provider ran but returned something that is not a usable token.

Timeout

The provider did not produce a token within its own deadline.

Other

Any other provider failure.

impl Eq for TokenSourceError

impl Error for TokenSourceError

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
