Enum MemoryError 

pub enum MemoryError {
    NotImplemented(&'static str),
    NotFound(String),
    InvalidArgument(String),
    Storage(String),
    Provider(String),
    Internal(String),
}

Errors produced by the memory subsystem.

Variants

NotImplemented(&'static str)

The requested feature isn’t implemented by the current provider.

v1’s BasicMemoryProvider returns this for summarization, rollups, and re-embed methods. The full Memory & Context Manager replaces the provider and implements all of these.

NotFound(String)

The requested chunk, session, or other entity could not be found.

InvalidArgument(String)

A caller passed an invalid argument (out-of-range importance, empty query, malformed predicate, etc.).

Storage(String)

A storage-layer error (SQLite, filesystem, embedding model load).

Provider(String)

A network or external-provider error (cloud embedder, cloud summarizer).

Internal(String)

An unexpected internal invariant was violated. Bug.

Trait Implementations

impl Debug for MemoryError

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

Formats the value using the given formatter.

impl Display for MemoryError

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

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.
