Enum MemoryError 

pub enum MemoryError {
    Sqlite {
        context: String,
        source: Error,
    },
    Io {
        context: String,
        source: Error,
    },
    Serde {
        context: String,
        source: Error,
    },
    Logic(String),
}

Errors produced by the memory store.

Variants

Sqlite

A SQLite operation failed. context describes what we were trying to do; source is the underlying sqlx::Error for chain inspection.

Fields

context: String

Human-readable description of the failing operation (e.g. “advance task”, “fts search”, “record token usage”).

source: Error

The underlying sqlx error.

Io

A filesystem operation failed. context describes what we were trying to do; source is the underlying std::io::Error.

Fields

context: String

Human-readable description of the failing operation (e.g. “create data dir”, “open audit log”).

source: Error

The underlying I/O error.

Serde

JSON serialization or deserialization failed.

Fields

context: String

Human-readable description of the failing operation.

source: Error

The underlying serde_json error.

Logic(String)

Domain-logic error with no foreign source — invalid arguments, missing rows, malformed input, etc.

Implementations

impl MemoryError

pub fn sqlite(context: impl Into<String>, source: Error) -> Self

Wrap a sqlx::Error with operation context.

pub fn io(context: impl Into<String>, source: Error) -> Self

Wrap a std::io::Error with operation context.

pub fn serde(context: impl Into<String>, source: Error) -> Self

Wrap a serde_json::Error with operation context.

pub fn logic(msg: impl Into<String>) -> Self

Construct a domain-logic error from a message.

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.

impl From<MemoryError> for KernexError

Bridge to the workspace-level aggregate error.

Boxes the typed MemoryError inside KernexError::Store so callers downstream can recover the structured cause via boxed.downcast_ref::<MemoryError>() and pattern-match on the concrete variant (e.g. MemoryError::Sqlite { source, .. } to inspect the underlying sqlx::Error).

fn from(err: MemoryError) -> Self

Converts to this type from the input type.
