Enum CaptureError 

pub enum CaptureError {
    Encode(EncodeError),
    Submit(SubmitError),
    Halted,
}

Errors returned by BusCaptureAdapter::capture.

Each variant maps to a SPEC-named failure mode at the dispatch boundary; the kernel’s fail-stop callback is the system response to CaptureError::Submit and CaptureError::Halted.

Variants

Encode(EncodeError)

The encoder rejected the message.

Submit(SubmitError)

The writer rejected the submit.

The adapter halt callback has fired before this error returns, so the kernel fail-stop path is already in motion when the caller observes it.

Halted

A prior capture observed a writer failure and the adapter has fail-stopped.

The halt callback fired on the original failure; subsequent captures short-circuit without re-entering the writer to keep the no-drop contract intact (a stuck or closed writer must not silently swallow captures).

Trait Implementations

impl Debug for CaptureError

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

Formats the value using the given formatter.

impl Display for CaptureError

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

Formats the value using the given formatter.

impl Error for CaptureError

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<EncodeError> for CaptureError

fn from(source: EncodeError) -> Self

Converts to this type from the input type.

impl From<SubmitError> for CaptureError

fn from(source: SubmitError) -> Self

Converts to this type from the input type.
