Enum ExecutionNonceError 

pub enum ExecutionNonceError {
    BadSchema {
        got: String,
    },
    Expired {
        now: i64,
        expires_at: i64,
    },
    BindingMismatch {
        field: &'static str,
    },
    InvalidSignature,
    Replayed,
    Encoding(String),
    Store(String),
}

All the reasons an execution nonce can fail verification.

Every variant is a hard deny on the kernel side. The nonce flow is fail-closed: schema, expiry, binding, signature, and replay checks all execute on every presented nonce and any failure short-circuits.

Variants

BadSchema

Schema did not equal EXECUTION_NONCE_SCHEMA.

Fields

got: String

Expired

Nonce has expired (now >= expires_at).

Fields

now: i64

expires_at: i64

BindingMismatch

Binding fields did not match the presented invocation.

Fields

field: &'static str

InvalidSignature

Ed25519 signature did not verify under the kernel’s public key.

Replayed

Nonce was already consumed (single-use).

Encoding(String)

Canonical JSON serialization failed during verification.

Store(String)

Replay store was unreachable; fail-closed.

Trait Implementations

impl Clone for ExecutionNonceError

fn clone(&self) -> ExecutionNonceError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ExecutionNonceError

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

Formats the value using the given formatter.

impl Display for ExecutionNonceError

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

Formats the value using the given formatter.

impl Error for ExecutionNonceError

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 From<ExecutionNonceError> for KernelError

fn from(err: ExecutionNonceError) -> Self

Converts to this type from the input type.

impl PartialEq for ExecutionNonceError

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
