Errors produced by a benchmark run.

Variants

ControlMessageTooLarge

A control frame exceeded the configured maximum.

Fields

actual: usize

Encoded message size.

maximum: usize

Configured maximum.

UnsupportedProtocolVersion

The peer selected no mutually supported protocol version.

DurationLimitExceeded

A requested test exceeds a server limit.

Fields

requested: Duration

Requested duration.

maximum: Duration

Server maximum.

Timeout

The operation timed out.

Fields

stage: &'static str

Human-readable stage name.

Cancelled

The caller cancelled the benchmark task.

ThroughputDeniedByPeer

The peer allows low-bandwidth probes but denies throughput measurements.

Peer

The peer rejected or failed a protocol operation.

Fields

code: u16

Stable wire error code.

message: String

Diagnostic message.

Network(String)

A host session or stream operation failed.

FlowStopped

The peer cleanly ended a flow-local measurement stream at its accounting deadline.

Protocol(String)

A protocol invariant was violated.

Codec(Error)

Control message serialization failed.

Io(Error)

I/O 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<Error> for Error

fn from(source: Error) -> Self

Converts to this type from the input type.
