Struct RefreshError 

pub struct RefreshError { /* private fields */ }

A failed key refresh: discovery, fetch, or a key set with nothing usable in it. The keys held before the attempt are kept.

Display is the whole cause chain, outermost first, joined with ": " (e.g. fetching the JWKS from https://…: request failed: …), so a log line needs no special formatting to show the root cause. RefreshError::kind is the coarse, matchable stage that failed.

Security

A configured issuer or jwks_uri may carry a credential: userinfo (https://user:pass@…, which the fetch sends as HTTP Basic auth) or a query string (…/jwks?key=…). Every URL in the message is therefore redacted — userinfo becomes ***@, a query ?*** and a fragment #***, while scheme, host, port and path stay, so the endpoint is still identifiable — and upstream errors are included without the URL they would otherwise repeat verbatim. The fetch itself uses the URL unchanged. The message still names the endpoints and repeats upstream error text, so it is for logs and operators: a public, unauthenticated endpoint (a health check reachable from outside, say) should report RefreshError::kind instead.

Implementations

impl Eq for RefreshError

impl Error for RefreshError

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
