Implementations§

source§

impl CoverageDataCollectorProxy

source

pub fn new(channel: AsyncChannel) -> Self

Create a new Proxy for fuchsia.fuzzer/CoverageDataCollector.

source

pub fn take_event_stream(&self) -> CoverageDataCollectorEventStream

Get a Stream of events from the remote end of the protocol.

§Panics

Panics if the event stream was already taken.

source

pub fn initialize( &self, eventpair: EventPair, process: Process ) -> QueryResponseFut<Options>

Registers the instrumented target process.

This method is called once per connection to set up:

  • The eventpair used to synchronize the start and end of code coverage collection.
  • The process Handle used to monitor the target process for errors.

This method must be called before the target process can call AddLlvmModule.

It returns the currently set options; see fuchsia.fuzzer.Controller/Configure.

Certain options determine sanitizer behaviors before main is called, and cannot subsequently be changed while the target process is running. This is the root cause of the constraint in Controller against modifying options during “long-running workflows”, i.e those that spawn target processes.

The channel is closed on FIDL error. Clients should not attempt to reconnect.

source

pub fn add_inline8bit_counters( &self, inline_8bit_counters: Vmo ) -> QueryResponseFut<()>

Adds a VMO with the code coverage of an LLVM module.

The VMO used to share inline 8-bit code-coverage edge counters for a single LLVM module in an instrumented target process.

Its ZX_PROP_NAME property must be set, and client and server implementations must agree on how to use it to uniquely identify the module. If the same module is added more than once by different processes, the module identifiers must match so that the code counters can be combined.

Its ZX_PROP_VMO_CONTENT_SIZE property must be set to the actual number of counters present.

It is an error to call this method without first calling |Initialize|.

The channel is closed on FIDL error. Clients should not attempt to reconnect.
