A capability, promise, transport or protocol failure.

Variants

UnknownCapability(u128)

A capability id is unknown to this kernel (forged or expired).

MethodNotGranted

A capability exists but the requested method is outside its grants.

Fields

method: String

Method that was attempted.

Escalation(&'static str)

An attenuation attempt would widen authority.

ReadOnly

A capability is read-only and the call mutates state.

PathNotGranted(String)

A path restriction rejected the call.

ToolPolicy(&'static str)

A tool policy rejected the call.

Revoked(u128)

The capability has been revoked or its provider disappeared.

BudgetExceeded(&'static str)

A budget was exhausted.

UnknownLane(u64)

The lane does not exist (or was destroyed).

UnknownChannel(u64)

The channel does not exist.

UnknownPromise(u64)

The promise does not exist.

PromiseCancelled(u64)

A promise was cancelled and can no longer be awaited.

PromiseAlreadyResolved(u64)

A promise was resolved twice.

UnresolvablePromise(u64)

The call references a promise that will never resolve.

Provider

The provider failed the call.

Fields

code: String

Stable provider-side code.

Domain(&'static str)

A translated Active evaluation failed.

Payload(String)

A payload is not a valid Active Infinity module.

Wire(&'static str)

The wire envelope is malformed.

CapabilityTable(&'static str)

The envelope’s capability table is malformed or oversized.

Transport(String)

A transport failed.

TransportUnavailable(&'static str)

A transport is unavailable in this build or on this host.

Timeout

A deadline elapsed before the call completed.

PipelinedCycle

The kernel detected a cycle in pipelined calls.

InvalidArgument(&'static str)

Invalid argument supplied by the caller.

Implementations

impl Error

pub const fn code(&self) -> &'static str

Permanent machine-readable code.

pub const fn is_fatal(&self) -> bool

True when the failure means the peer sent something hostile.

Trait Implementations

impl Clone for Error

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

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

Formats the value using the given formatter.

impl Eq for Error

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.

impl From<Error> for Error

fn from(error: Error) -> Self

Converts to this type from the input type.

impl PartialEq for Error

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

Equality operator ==.

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

Inequality operator !=.

impl StructuralPartialEq for Error
