Enum SessionError 

pub enum SessionError {
    NotFound,
    Invalid(String),
    Backend(String),
}

Errors a session store can return. Kept as a flat enum so the shape is stable across backends; backend-specific detail goes in the wrapped message.

Variants

NotFound

The id did not exist, or was present but has expired.

Invalid(String)

The id was present but failed integrity / signature checks (cookie-only stores) or was malformed (server-backed stores).

Backend(String)

Transport / storage layer failure (network, disk, etc.).

Trait Implementations

impl Clone for SessionError

fn clone(&self) -> SessionError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SessionError

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

Formats the value using the given formatter.

impl Display for SessionError

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

Formats the value using the given formatter.

impl Error for SessionError

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>)
