Variants

InvalidMetadataKey

The metadata key is invalid.

Fields

value: String

Invalid key text.

source: PermissionMetadataKeyError

Key parse error.

UnclosedContext

A context selector starts with { but does not end with }.

EmptyContext

The context selector contains no entries.

InvalidContextEntry(String)

A context entry is not key=value.

InvalidContextValue

A context entry contains an unsupported value.

Fields

key: String

Context key.

value: String

Invalid context value.

DuplicateContextKey(String)

The same context key appears more than once.

InvalidDomain(String)

The built-in domain value is invalid.

InvalidWorld(String)

The built-in loaded-world value is invalid.

InvalidContextKey

Implementations

impl PermissionMetadataExpressionError

fn from_context_error(error: PermissionExpressionContextError) -> Self

Trait Implementations

impl Clone for PermissionMetadataExpressionError

fn clone(&self) -> PermissionMetadataExpressionError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PermissionMetadataExpressionError

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

Formats the value using the given formatter.

impl Display for PermissionMetadataExpressionError

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

impl Eq for PermissionMetadataExpressionError

impl Error for PermissionMetadataExpressionError

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 PermissionMetadataExpressionError

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

Equality operator ==.

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

Inequality operator !=.
