Enum SessionError 

pub enum SessionError {
    Io(Error),
    Serialize(Error),
    NotFound {
        session_id: String,
    },
    Locked {
        session_id: String,
    },
    Task(String),
}

Errors from session I/O.

Variants

Io(Error)

Serialize(Error)

NotFound

Fields

session_id: String

Locked

Returned by SessionStore when an exclusive advisory lock could not be acquired on the target session file within the retry budget — typically because another process is currently writing the same session.

Fields

session_id: String

Task(String)

Async runtime failure when spawning blocking I/O work (e.g. tokio::task::JoinError).

Trait Implementations

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, __formatter: &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>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.
