A precise task-trace validation failure.

Variants

Malformed

A tag’s class-specific fields were not canonical.

Fields

index: usize

Trace offset.

raw: u32

Rejected raw tag.

StaleGeneration

A response came from an earlier or future context generation.

Fields

index: usize

Trace offset.

expected: u8

Required generation.

observed: u8

Observed generation.

WrongContext

A response was routed to the wrong scheduler context.

Fields

index: usize

Trace offset.

expected: u8

Required context.

observed: u8

Observed context.

UnexpectedTask

A canonical task appeared at the wrong serial-baseline position.

Fields

index: usize

Trace offset.

expected: DecodedTaskTag

Required task.

observed: DecodedTaskTag

Observed task.

Truncated

The trace ended before all 1,258 tasks retired.

Fields

expected: usize

Required trace length.

observed: usize

Observed trace length.

Extra

The trace continued after all required tasks retired.

Fields

index: usize

First unexpected trace offset.

raw: u32

First unexpected raw tag.

CountMismatch

Class counts did not equal the protocol constants.

Fields

expected: TaskCounts

Required counts.

observed: TaskCounts

Observed counts.

Trait Implementations

impl Clone for TaskTraceError

fn clone(&self) -> TaskTraceError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for TaskTraceError

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

Formats the value using the given formatter.

impl Display for TaskTraceError

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

Formats the value using the given formatter.

impl Error for TaskTraceError

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 PartialEq for TaskTraceError

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

Tests for self and other values to be equal, and is used by ==.

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

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