Struct InstrumentedHandle 

pub struct InstrumentedHandle { /* private fields */ }

Single control handle for the InstrumentedDriver test middleware. Exposes both the operation log (for assertions) and the fault queue (for injecting failures). Cheaply cloneable; every clone refers to the same shared state.

Implementations

impl InstrumentedHandle

pub fn len(&self) -> usize

Get the number of logged operations

pub fn is_empty(&self) -> bool

Check if the log is empty

pub fn clear(&self)

Clear the log

pub fn pop(&self) -> (Operation, ExecResponse)

Remove and return the first operation from the log

pub fn pop_op(&self) -> Operation

pub fn inject_fault(&self, fault: Fault)

Queue a fault to fire on the next driver exec call. Faults fire in FIFO order across all connections produced by the driver.
