class CoverageDataProvider
Defined at line 8932 of file fidling/gen/src/sys/fuzzing/fidl/fuchsia.fuzzer/hlcpp/fuchsia/fuzzer/cpp/fidl.h
Provides the process Handles and VMOs used to share code coverage to the fuzzing engine.
This protocol is implemented by `test_manager`'s `fuzz_coverage` component. The fuzzing engine
acts as a client, although it does not connect directly. Instead the `fuzz_test_runner` makes
the connection and passes it off to fuzzing engine on process start. It allows the engine to
retrieve the coverage-related Handles published by instrumented target processes.
The channel is closed on FIDL error. Clients should exit and not attempt to reconnect.

void ~CoverageDataProvider ()void SetOptions (::fuchsia::fuzzer::Options options)Sets the options to be returned by `fuchsia.fuzzer.CoverageDataCollector/Initialize`.
void WatchCoverageData (WatchCoverageDataCallback callback)Provides coverage data collected from multiple processes.
Returns a vector of `CoverageData` structs containing the information provided by clients of
`fuchsia.fuzzer.CoverageDataCollector`. This method uses the "hanging get" pattern: The
initial call will immediately return whatever data is available, up to `MAX_COVERAGE_DATA`.
If no fuzzed components have been started yet, this be an empty vector. If there are more
than `MAX_COVERAGE_DATA` elements available, the remainder are retained for subsequent
calls. If there is no more data available, subsequent calls will block until new coverage
data is available.
