Enum SessionStoreError 

#[non_exhaustive]
pub enum SessionStoreError {
    Encode(String),
    Decode(String),
    Backend(String),
}

Errors returned by SessionStore implementations.

Mirrors the three-variant shape used by tower-sessions: encode/decode errors from the record (de)serialization, and catch-all backend errors from the storage layer.

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.

Encode(String)

Failed to encode a SessionRecord (e.g. serde serialization error).

Decode(String)

Failed to decode a SessionRecord (e.g. corrupt data in the backend).

Backend(String)

Backend error (e.g. connection failure, transient storage error).

Trait Implementations

impl Debug for SessionStoreError

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

Formats the value using the given formatter.

impl Display for SessionStoreError

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

Formats the value using the given formatter.

impl Error for SessionStoreError

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.
