Enum Error 

#[non_exhaustive]
pub enum Error {
    IllegalTransition {
        from: &'static str,
        to: &'static str,
    },
    Integrity {
        expected: String,
        actual: String,
    },
    NotFound {
        what: String,
    },
    Unauthorized,
    Malformed {
        what: String,
    },
    Backend {
        detail: String,
    },
}

The error surface shared across Deputy. Kept small and #[non_exhaustive] so new variants can be added without a breaking change.

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.

IllegalTransition

An artifact was asked to move along an edge the state machine does not permit. See docs/PIPELINE.md §7.

Fields

from: &'static str

to: &'static str

Integrity

A downloaded artifact’s content hash did not match its pinned, expected hash.

Fields

expected: String

actual: String

NotFound

A referenced entity (artifact, repo, record) was not found.

Fields

what: String

Unauthorized

The current actor lacks a valid mID session for a privileged operation.

Malformed

Input could not be parsed into a well-formed domain value.

Fields

what: String

Backend

A lower layer (storage, database, crypto, I/O) failed. Carries a human-readable detail; the originating crate keeps the richer typed error.

Fields

detail: String

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

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, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for Error

impl Error for Error

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.

impl PartialEq for Error

fn eq(&self, other: &Error) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
