Enum Error

pub enum Error {
    Cxx(Exception),
    IO(Error),
    PoisonedMutex,
    LayerStopped,
    TimedOut,
    FlushFailed,
}

Generic error from the Perfetto SDK

Variants

Cxx(Exception)

A generic C++ exception occurred in the C++ code.

IO(Error)

A generic OS-level IO error occurred.

PoisonedMutex

An internal Mutex is poisoned due to some other thread panicking while holding the mutex.

LayerStopped

An operation can’t complete because someone already called layer.stop() on the layer.

TimedOut

An operation timed out according to one of the timeouts set in the layer builder.

FlushFailed

A flush failed due to some unknown reason.

This is not necessarily separate from the TimedOut case; we simply don’t know the reason why the flush failed.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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<Error> for Error

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<Exception> for Error

fn from(source: Exception) -> Self

Converts to this type from the input type.
