Enum MlPersistenceError 

pub enum MlPersistenceError {
    Backend(String),
    Corruption(String),
}

Errors surfaced by a persistence backend. Intentionally small — callers convert into their own error types.

Variants

Backend(String)

Underlying store returned an error. Message is backend-specific.

Corruption(String)

Value was expected to parse as JSON but did not.

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)
