Enum OperatorKeyError 

#[non_exhaustive]
pub enum OperatorKeyError {
    BlankField {
        index: usize,
        field: &'static str,
    },
    Unreadable {

        path: PathBuf,

        key_id: String,

Failures that stop OperatorKeys::load, and with it the broker.

Every variant is a startup error. A key set that a broker cannot load is never downgraded to a smaller one: a signature checked against a partial trust set is a signature check that silently does nothing.

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.

BlankField

A key_id or a principal is blank. Neither can be matched against a signed record, so the entry could never authorize anything.

Fields

index: usize

Zero-based position of the entry in the configured array.

field: &'static str

Name of the blank field, key_id or principal.

Unreadable

The public_key_path could not be read.

Fields

key_id: String

The entry’s key_id.

path: PathBuf

The path that could not be read.

source: Error

The underlying I/O failure.

Malformed

The file does not hold a raw Ed25519 public key.

Fields

key_id: String

The entry’s key_id.

path: PathBuf

The path that was read.

found: usize

How many bytes the file holds.

DuplicateKeyId

Two entries share a key_id. A signed record names one key, so a repeated id makes the key it selects depend on the file order.

Fields

key_id: String

The repeated key_id.

DuplicatePrincipal

Two entries bind the same principal. The broker checks that a record’s claimed author is the principal bound to the signing key, and a principal with two keys makes that check ambiguous.

Fields

principal: String

The repeated principal.

first: String

The key_id that claimed the principal first.

second: String

The key_id that claimed it again.

Trait Implementations

impl Debug for OperatorKeyError

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

Formats the value using the given formatter.

impl Display for OperatorKeyError

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

Formats the value using the given formatter.

impl Error for OperatorKeyError

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.
