Enum HistogramQueryError 

pub enum HistogramQueryError {
    BucketOutOfBounds {
        index: usize,
        buckets: usize,
    },
    InvalidQuantile,
    SaturatedCount,
}

Why a histogram cannot supply an exact reporting projection.

Variants

BucketOutOfBounds

The index does not name one of the configured finite upper bounds.

Fields

index: usize

Requested zero-based bound index.

buckets: usize

Number of configured finite upper bounds.

InvalidQuantile

A nearest-rank fraction must satisfy 0 < numerator <= denominator.

SaturatedCount

A required count or cumulative sum is at the u64::MAX cap.

Trait Implementations

impl Clone for HistogramQueryError

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for HistogramQueryError

impl Debug for HistogramQueryError

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

Formats the value using the given formatter.

impl Display for HistogramQueryError

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

Formats the value using the given formatter.

impl Eq for HistogramQueryError

impl Error for HistogramQueryError

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 PartialEq for HistogramQueryError

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

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
