Manifest-loading failure taxonomy.

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.

ParseError(String)

TOML parse or UTF-8 decode failure.

MissingRequired(&'static str)

A required field was absent (reserved for future custom checks beyond what serde(deny_unknown_fields) already enforces).

TierBackendMismatch

Compliance-tier / DEK-backend pair is inconsistent.

Fields

tier: u8

Declared tier.

backend: String

Declared backend.

SoftwareKekProductionRefused

software-kek is allowed only on Tier-0 dev runs; production runtimes (runtime_current > 0.15) reject it.

Fields

current: String

Declared current runtime version.

VersionMismatch

runtime_max lexicographically precedes runtime_current (illegal because the shell would claim forward-compat to a version less than the one it tested).

UnknownField(String)

Reserved — future custom deserializer returns this when extracting the offending key from a deny_unknown_fields failure.

InvalidValue

Field failed a validation predicate (e.g. malformed semver).

Fields

field: &'static str

Field name whose value was rejected.

reason: String

Human-readable reason.

Trait Implementations

impl Debug for ManifestError

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

Formats the value using the given formatter.

impl Display for ManifestError

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

Formats the value using the given formatter.

impl Error for ManifestError

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.
