Enum SessionError 

pub enum SessionError {
    Io(Error),
    Serde(Error),
    Db(SqlxError),
    NotFound(String),
    InvalidForkPoint(String),
    CondensationOverlap(String),
    Llm(LlmError),
    AlreadyLocked(String),
}

Errors produced by the session persistence, replay, and fork engines.

Variants

Io(Error)

Filesystem I/O failed while reading or appending to an event log.

Serde(Error)

A SessionEvent line failed to (de)serialize.

Db(SqlxError)

The acp_sessions metadata store returned a database error.

NotFound(String)

A lookup by zeph_common::SessionId found no matching session.

InvalidForkPoint(String)

A fork was requested at a seq beyond the source session’s last_seq.

CondensationOverlap(String)

A condensation or compaction range overlapped a previously replaced range (INV-SP-4).

Llm(LlmError)

Condensation summarization failed (LLM call error or timeout).

AlreadyLocked(String)

crate::log::SessionEventLog::open_exclusive found another process already holding the session’s advisory write lock.

Trait Implementations

impl Debug for SessionError

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

Formats the value using the given formatter.

impl Display for SessionError

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

Formats the value using the given formatter.

impl Error for SessionError

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.
