Enum MemoryError 

#[non_exhaustive]
pub enum MemoryError {
    Backend(Box<dyn Error + Sync + Send>),
    Policy(String),
    Internal(String),
}

Re-exports of the core memory abstractions so callers only need a single dependency on rig-memory for both the trait/backend and the policies. Errors produced by a ConversationMemory backend.

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.

Backend(Box<dyn Error + Sync + Send>)

The backing store failed to load, append, or clear messages.

Policy(String)

A history-shaping filter or policy rejected the loaded history.

Internal(String)

An internal invariant was violated (e.g. a poisoned in-process lock). Distinct from MemoryError::Backend, which is reserved for failures of the underlying conversation store.

Implementations

impl MemoryError

pub fn backend<E>(source: E) -> MemoryError

where E: Into<Box<dyn Error + Sync + Send>>,

Wrap an arbitrary error from a backend implementation.

Trait Implementations

impl Debug for MemoryError

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

Formats the value using the given formatter.

impl Display for MemoryError

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

Formats the value using the given formatter.

impl Error for MemoryError

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.
