Enum SessionError 

pub enum SessionError {
    MutationMidTurn {
        op: &'static str,
    },
    ChecksumMismatch {
        journal: u32,
        program: u32,
    },
    Runtime(RuntimeError),
}

Errors from session-level operations (distinct from VM RuntimeErrors, which are wrapped).

Variants

MutationMidTurn

A turn-boundary-only mutation (set_var / go_to_path / load_state) was attempted mid-turn (status Active). Drain the turn first.

Fields

op: &'static str

ChecksumMismatch

The program checksum in a journal does not match the program being restored/replayed against, and no fast-restore checkpoint was usable.

Fields

journal: u32

program: u32

Runtime(RuntimeError)

A wrapped VM error.

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.

impl From<RuntimeError> for SessionError

fn from(source: RuntimeError) -> Self

Converts to this type from the input type.
