Struct Comparison 

pub struct Comparison {
    pub comparator: Comparator,
    pub threshold: f64,
}

A comparator and its threshold, as in <=10.

Fields

comparator: Comparator

Test between a value and Self::threshold.

threshold: f64

Value a sample is compared with.

Implementations

impl Comparison

pub fn holds(self, value: f64) -> bool

Returns whether value passes the comparison. A NaN value never passes, under any comparator.

pub fn check(self) -> Result<(), ComparisonError>

Checks that the threshold is finite, as a threshold parsed with FromStr always is.

Errors

Returns ComparisonError::BadThreshold for a threshold that is infinite or NaN.

Trait Implementations

impl Clone for Comparison

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 Comparison

impl Debug for Comparison

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

Formats the value using the given formatter.

impl Display for Comparison

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

Writes the comparator and the threshold with no space between, as in <=10.

impl FromStr for Comparison

fn from_str(raw: &str) -> Result<Self, Self::Err>

Reads a comparator followed by a finite threshold, with optional spaces around the comparator and the threshold.

type Err = ComparisonError

The associated error which can be returned from parsing.

impl PartialEq for Comparison

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

Equality operator ==.

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

Inequality operator !=.
