Enum RepositoryError 

pub enum RepositoryError {
    SessionNotFound,
    SessionFamilyNotFound,
    Conflict,
    InvalidState,
    Backend {
        message: String,
    },
}

Repository boundary errors for session persistence.

Variants

SessionNotFound

The requested session record was not found.

SessionFamilyNotFound

The requested session family record was not found.

Conflict

An optimistic or compare-and-swap style write lost a race.

InvalidState

Stored session data was invalid or inconsistent.

Backend

A backend-specific operation failed.

Fields

message: String

Safe, caller-facing backend failure summary.

Implementations

impl RepositoryError

pub fn backend(message: impl Into<String>) -> Self

Creates a backend error with a safe, caller-facing message.

Trait Implementations

impl Clone for RepositoryError

fn clone(&self) -> RepositoryError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RepositoryError

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

Formats the value using the given formatter.

impl Display for RepositoryError

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

Formats the value using the given formatter.

impl Error for RepositoryError

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<RepositoryError> for RepositoryError

fn from(value: RepositoryError) -> Self

Converts to this type from the input type.

impl From<RepositoryError> for SessionError

fn from(source: RepositoryError) -> Self

Converts to this type from the input type.

impl PartialEq for RepositoryError

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