Enum hdrhistogram::serialization::DeserializeError

pub enum DeserializeError {
    IoError(Error),
    InvalidCookie,
    UnsupportedFeature,
    UnsuitableCounterType,
    InvalidParameters,
    UsizeTypeTooSmall,
    EncodedArrayTooLong,
}

Errors that can happen during deserialization.

Variants

IoError(Error)

An i/o operation failed.

InvalidCookie

The cookie (first 4 bytes) did not match that for any supported format.

UnsupportedFeature

The histogram uses features that this implementation doesn't support (yet), so it cannot be deserialized correctly.

UnsuitableCounterType

A count exceeded what can be represented in the chosen counter type.

InvalidParameters

The histogram instance could not be created because the serialized parameters were invalid (e.g. lowest value, highest value, etc.)

UsizeTypeTooSmall

The current system's pointer width cannot represent the encoded histogram.

EncodedArrayTooLong

The encoded array is longer than it should be for the histogram's value range.

Trait Implementations

impl Debug for DeserializeError

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

Formats the value using the given formatter.

impl Display for DeserializeError

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

Formats the value using the given formatter.

impl Error for DeserializeError

fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

fn backtrace(&self) -> Option<&Backtrace>

🔬 This is a nightly-only experimental API. (backtrace)

Returns a stack backtrace, if available, of where this error occurred.

fn description(&self) -> &str

👎 Deprecated since 1.42.0:

use the Display impl or to_string()

if let Err(e) = "xc".parse::<u32>() { // Print e itself, no need for description(). eprintln!("Error: {}", e); }

fn cause(&self) -> Option<&dyn Error>

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

impl From<Error> for DeserializeError

fn from(e: Error) -> Self

Performs the conversion.
