Struct ReplayTraceExhausted 

pub struct ReplayTraceExhausted {
    pub recorded: usize,
    pub attempted: usize,
}

The error Driver::read wraps in DriverError::Operation when the configured PV tag is read after every recorded sample has already been consumed.

A correctly captured trace paired with a correctly behaving engine should never reach this: MrftEngine::step is a documented no-op once it has returned Action::Complete once (see crates/bhtune-core/tests/golden_replay.rs’s own note on this), so a caller that stops polling as soon as completion is observed – exactly the shape that test and this module’s own end-to-end test both use – never triggers it. Seeing this in practice means either the trace’s tick count doesn’t actually cover a real MRFT completion, or the engine driving this driver has a genuine regression that fails to complete in time.

Fields

recorded: usize

How many samples this driver was constructed with.

attempted: usize

The 1-based read attempt number that failed (recorded + 1, recorded + 2, …).

impl Eq for ReplayTraceExhausted

impl Error for ReplayTraceExhausted

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 ReplayTraceExhausted

fn eq(&self, other: &ReplayTraceExhausted) -> 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.
