Enum Error 

#[non_exhaustive]
pub enum Error {
    NotImplemented {
        operation: &'static str,
    },
    GateFailed {
        reason: String,
    },
    Invalid {
        reason: String,
    },
    SyncConflict {
        reason: String,
    },
}

Everything an onevcs operation can fail with.

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.

NotImplemented

The request parsed and validated, but the seam behind it has no implementation yet. The CLI reports this as exit code 70.

Fields

operation: &'static str

The contract operation that was asked for, e.g. Vcs::open_session.

GateFailed

A verification gate, or the host’s required checks, reported failure. The CLI reports this as exit code 1.

Fields

reason: String

What failed, naming the check where the host reported one.

Invalid

Input was rejected at a trust boundary — a malformed registry document, a rules file that does not parse, an unusable argument. The CLI reports this as exit code 2.

Fields

reason: String

What was rejected and why.

SyncConflict

The base moved under a publication and the bounded resolve-and-requeue did not converge. The CLI reports this as exit code 3.

Fields

reason: String

The conflict that survived the bounded retry.

Trait Implementations

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

Formats the value using the given formatter.

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.
