Enum SessionKvError 

pub enum SessionKvError {
    LimitExceeded {
        operation: &'static str,
        key: String,
        limit: SessionKvLimitKind,
    },

    },

}

Variants

LimitExceeded

A bound was exceeded. key is rendered lossily for the message only; the value never appears.

Fields

operation: &'static str

key: String

limit: SessionKvLimitKind

InvalidKey

An empty key, or one the implementation otherwise refuses.

Fields

operation: &'static str

key: String

reason: &'static str

Backend

The backing store failed for a reason the caller cannot fix by retrying with a smaller value.

Fields

operation: &'static str

message: String

impl Eq for SessionKvError

impl Error for SessionKvError

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
