Enum ProfileError 

pub enum ProfileError {
    Unknown {
        reason: String,
        backtrace: BackTrace,
    },
    NotRegistered {
        backtrace: BackTrace,
    },
    NotMeasured {
        backtrace: BackTrace,
    },
    Launch(LaunchError),
    Server(Box<ServerError>),
}

An error during profiling.

Variants

Unknown

An unknown error happened during profiling

Fields

reason: String

The caused of the error

backtrace: BackTrace

The captured backtrace.

NotRegistered

No profiling was registered

Fields

backtrace: BackTrace

The captured backtrace.

NotMeasured

The profiled window resolved no device timing.

Distinct from a zero duration, which is a measurement that came back instant. This is the absence of one: nothing the window enqueued was timestamped, so the backend has nothing to report. A caller that only wants a number can treat it as zero; a caller comparing candidates must not, because an absence that reads as zero is the fastest result there is and wins every comparison it enters.

Fields

backtrace: BackTrace

The captured backtrace.

Launch(LaunchError)

A launch error happened during profiling

Server(Box<ServerError>)

An execution error happened during profiling

Trait Implementations

impl Clone for ProfileError

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ProfileError

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ProfileError

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for ProfileError

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

Formats the value using the given formatter.

impl Error for ProfileError

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<&ServerError> for ProfileError

A failure during a profiling window invalidates the measurement, whatever the failure was. Every backend answers a launch, write or replay failure this way, so the conversion lives here rather than five times over.

fn from(error: &ServerError) -> Self

Converts to this type from the input type.

impl From<Box<ServerError>> for ProfileError

fn from(source: Box<ServerError>) -> Self

Converts to this type from the input type.

impl From<LaunchError> for ProfileError

fn from(source: LaunchError) -> Self

Converts to this type from the input type.

impl Serialize for ProfileError

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
