Failure while capturing or restoring versioned speculative state.

Variants

Null

A required native session or output pointer was null.

BadSequence

The sequence id is outside the configured session range.

NotQuiescent

A draft proposal has not yet been completed with accept.

SizeChanged

Native state changed size between the size and copy calls.

Fields

expected: usize

Size returned by the initial query.

actual: usize

Size required or written by the copy call.

BufferTooSmall

Native reported that the supplied buffer was too small without a size.

Unavailable

The active native implementation did not expose complete state.

Invalid

The supplied state failed its exact version/configuration checks.

Overflow

Native state size arithmetic overflowed.

Exception

A C++ exception was contained by the speculative-state shim.

Excessive

State exceeded the safe allocation/input bound.

Fields

size: usize

Requested or supplied byte count.

maximum: usize

Inclusive safe bound.

Unknown(u32)

Native returned a status unknown to this binding revision.

Trait Implementations

impl Clone for SpeculativeStateError

fn clone(&self) -> SpeculativeStateError

impl Eq for SpeculativeStateError

impl Error for SpeculativeStateError

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
