Enum DenyReason 

#[non_exhaustive]
pub enum DenyReason {
    CapabilityDenied,
    InstanceMismatch,
    OperationRestricted,
    NotImplemented,
}

Reason an effect was denied during authorization.

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.

CapabilityDenied

CapabilityMask lacks the bit required by the principal/op pair.

InstanceMismatch

Effect’s branded instance does not match the authorize call site.

OperationRestricted

Op type is restricted under the current policy (reserved for future per-op deny refinement).

NotImplemented

Authorization path not yet wired for this op variant.

Trait Implementations

impl Clone for DenyReason

fn clone(&self) -> DenyReason

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DenyReason

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

Formats the value using the given formatter.

impl Display for DenyReason

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

Formats the value using the given formatter.

impl Error for DenyReason

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 DenyReason

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