Errors arose out while accessing various interpreter data.

Variants

SetSubtraceLenFailed

Fields

requested_subtrace_len: usize

trace_position: TracePos

trace_len: usize

Errors occurred when trace_len - trace_position < requested_subtrace_len.

SetSubtraceLenAndPosFailed

Fields

requested_pos: TracePos

requested_subtrace_len: usize

trace_len: usize

Errors occurred when requested_subtrace_len != 0 && requested_pos + requested_subtrace_len > trace_len.

NoElementAtPosition

Fields

position: TracePos

trace_len: usize

Errors occurred when Fold FSM tries to obtain stream generation by value_pos from a trace, but this value_pos is bigger than the trace length.

NoStreamState

Fields

state: ExecutedState

Errors occurred when Fold FSM tries to obtain stream generation by value_pos from a trace, but such state doesn’t belong to values in streams (it doesn’t contain a generation).

Trait Implementations

impl Debug for KeeperError

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

Formats the value using the given formatter.

impl Display for KeeperError

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

Formats the value using the given formatter.

impl Error for KeeperError

fn source(&self) -> Option<&(dyn Error + 'static)>

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, demand: &mut Demand<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type based access to context intended for error reports.

impl From<KeeperError> for MergeError

fn from(source: KeeperError) -> Self

Converts to this type from the input type.

impl From<KeeperError> for StateFSMError

fn from(source: KeeperError) -> Self

Converts to this type from the input type.

impl From<KeeperError> for TraceHandlerError

fn from(source: KeeperError) -> Self

Converts to this type from the input type.

impl PartialEq<KeeperError> for KeeperError

fn eq(&self, other: &KeeperError) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
