Enum hdrhistogram::errors::SubtractionError

pub enum SubtractionError {
    SubtrahendValueExceedsMinuendRange,
    SubtrahendCountExceedsMinuendCount,
}

Errors that can occur when subtracting another histogram.

Variants

SubtrahendValueExceedsMinuendRange

The other histogram includes values that do not fit in this histogram's range. Only possible when auto resize is disabled.

SubtrahendCountExceedsMinuendCount

The other histogram includes counts that are higher than the current count for a value, and counts cannot go negative. The subtraction may have been partially applied to some counts as this error is returned when the first impossible subtraction is detected.

Trait Implementations

impl Clone for SubtractionError

fn clone(&self) -> SubtractionError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Copy for SubtractionError

impl Debug for SubtractionError

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

Formats the value using the given formatter.

impl Display for SubtractionError

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

Formats the value using the given formatter.

impl Eq for SubtractionError

impl Error for SubtractionError

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 1.41.0:

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 PartialEq<SubtractionError> for SubtractionError

fn eq(&self, other: &SubtractionError) -> bool

This method tests for self and other values to be equal, and is used by ==.

#[must_use] fn ne(&self, other: &Rhs) -> bool

This method tests for !=.
