Enum PermissionsError 

#[non_exhaustive]
pub enum PermissionsError {
    Collision {
        collision_count: usize,
        hash_id: u64,
        permissions: Vec<String>,
    },
}

Category-native permission errors.

These errors model permission-related problems. Use directly in permission validation and authorization flows.

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.

Collision

Permission collision detected when multiple permissions hash to the same value.

Fields

collision_count: usize

Number of permissions that collide.

hash_id: u64

The 64-bit hash ID that has collisions.

permissions: Vec<String>

List of permission names that collide.

Implementations

impl PermissionsError

pub fn collision(hash_id: u64, permissions: Vec<String>) -> Self

Create a permission collision error with collision details.

This constructor calculates the collision_count from the provided list.

Trait Implementations

impl Debug for PermissionsError

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

Formats the value using the given formatter.

impl Display for PermissionsError

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

Formats the value using the given formatter.

impl Error for PermissionsError

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<PermissionsError> for Error

fn from(source: PermissionsError) -> Self

Converts to this type from the input type.

impl UserFriendlyError for PermissionsError

fn user_message(&self) -> String

User-facing message that is clear, actionable, and non-technical.

fn developer_message(&self) -> String

Technical message with detailed information for developers and logs.

fn support_code(&self) -> String

Unique support reference code for customer service and troubleshooting.

fn severity(&self) -> ErrorSeverity

Error severity level for proper handling and alerting.

fn suggested_actions(&self) -> Vec<String>

Suggested user actions for resolving the error.

fn is_retryable(&self) -> bool

Whether this error should be retryable by the user.
