Enum Fault 

#[non_exhaustive]
pub enum Fault {
    Panic {
        message: String,
    },
    CapabilityViolation {
        token_id: String,
        capability: Capability,
    },
    TokenExpired {
        token_id: String,
        expires_at_epoch_s: u64,
    },
    ProtocolViolation {
        detail: String,
    },
    PolicyDenied {
        reason: String,
    },
}

Structured error type for kernel dispatch failures.

Unlike KernelError (which covers all kernel operations including setup), Fault represents runtime dispatch failures that callers can match on to decide recovery strategy.

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.

Implementations

impl Fault

pub fn from_policy_error(err: PolicyError) -> Fault

pub fn from_kernel_error(err: KernelError) -> Fault

Trait Implementations

impl Clone for Fault

fn clone(&self) -> Fault

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Fault

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Fault

fn deserialize<__D>( __deserializer: __D, ) -> Result<Fault, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Fault

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

Formats the value using the given formatter.

impl Error for Fault

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 Fault

fn eq(&self, other: &Fault) -> 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.

impl Serialize for Fault

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for Fault
