}

Failure to compile a policy from a database snapshot.

Variants

NotAnAuthzDatabase(String)

The snapshot does not carry the reserved authz schema.

Incomplete

A policy entity is missing a required attribute.

Fields

entity: &'static str

Kind of policy entity (tuple, permission, …).

eid: String

Entity id in the authz database.

attribute: &'static str

The attribute that is missing.

BadValue

A value could not be read as the schema’s type.

Fields

attribute: &'static str

The attribute.

eid: String

Entity id in the authz database.

expected: &'static str

The expected shape.

UndefinedView

A binding names a view the policy does not define. Fails compilation rather than silently dropping a restriction.

Fields

relation: String

Relation the binding attaches to.

object: String

Object the binding attaches to.

view: String

The missing view name.

UnsupportedFilter

A view names a filter type this build does not implement.

Fields

view: String

The view name.

kind: String

The filter type read from policy data.

Trait Implementations

impl Clone for PolicyError

fn clone(&self) -> PolicyError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PolicyError

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

Formats the value using the given formatter.

impl Display for PolicyError

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

Formats the value using the given formatter.

impl Eq for PolicyError

impl Error for PolicyError

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<PolicyError> for RefreshError

fn from(source: PolicyError) -> Self

Converts to this type from the input type.

impl PartialEq for PolicyError

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

Equality operator ==.

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

Inequality operator !=.
