Enum Error 

pub enum Error {
    NotOperational {
        current: State,
    },
    SelfTestFailed {
        test: &'static str,
    },
    ConditionalTestFailed {
        reason: &'static str,

Errors surfaced by the module boundary.

Every variant is constructed with a &'static str description so that formatting is allocation-free; this lets the module report failures even from no_std contexts and from within the self-test runner itself.

Variants

NotOperational

A service was invoked while the module was not in the Operational state.

Fields

current: State

The state the module was actually in when the call arrived.

SelfTestFailed

A power-up self-test failed. The module is now in the Error state.

Fields

test: &'static str

Name of the failing test, supplied by its SelfTest implementation.

ConditionalTestFailed

A conditional self-test (e.g. DRBG CRNGT, pairwise consistency) failed during operation. The module is now in the Error state.

Fields

reason: &'static str

Short description of the failing check.

AlreadyInitialized

initialize was called while the module was already past PowerOff. This is not itself a FIPS violation — it just means a second caller raced with the first. The first call’s outcome is authoritative; the race loser should read state to find out.

InvalidInput

A cryptographic service was called with input bytes that do not encode a valid domain element (for example, a scalar that is zero or not less than the group order, or a point that is not a canonical encoding on the curve). This is distinct from a self-test failure: the module is still operational; the caller supplied out-of-range bytes. Algorithm primitives should return this rather than silently substituting a default.

AlgorithmRestricted

A service was invoked that is not permitted under the active AlgorithmProfile. The module is still operational — the algorithm exists but is restricted by policy. Switch to a less restrictive profile (which requires a process restart) or use an alternative algorithm that is permitted.

Fields

service: Service

The specific service that was blocked.

NotImplemented

A service was invoked for an algorithm that exists in the Service enum but whose implementation has not yet been completed. Stub crates return this. The algorithm is recognized by the profile system and its gate will pass if the profile permits it, but the actual cryptographic operation is not yet available.
