Enum SessionBackendConfigError 

#[non_exhaustive]
pub enum SessionBackendConfigError {
    MissingRedisUrl,
    InvalidRedisUrl(String),
    RedisFeatureDisabled,
}

Errors that can occur when resolving the session backend configuration.

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.

MissingRedisUrl

Redis was selected, but no URL was provided.

InvalidRedisUrl(String)

The provided Redis URL could not be parsed.

RedisFeatureDisabled

Redis was selected, but the redis crate feature is not enabled.

Trait Implementations

impl Debug for SessionBackendConfigError

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

Formats the value using the given formatter.

impl Display for SessionBackendConfigError

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

Formats the value using the given formatter.

impl Error for SessionBackendConfigError

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 PartialEq for SessionBackendConfigError

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