Trait KeyValueStoreError 

pub trait KeyValueStoreError:
    Error
    + From<Error>
    + Debug
    + Send
    + Sync
    + 'static {
    const BACKEND: &'static str;

    // Provided method
    fn must_reload_view(&self) -> bool { ... }
}

The error type for the key-value stores.

Required Associated Constants

const BACKEND: &'static str

The name of the backend.

Provided Methods

fn must_reload_view(&self) -> bool

Returns true if this error represents a journal resolution failure, which may leave storage in an inconsistent state requiring a view reload.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
