Struct Quota 

pub struct Quota { /* private fields */ }

An upper or lower bound for metrics.

Implementations

impl Quota

pub fn new(bound: f64, upper: bool) -> Self

Creates a quota with the given bound and whether it is an upper bound.

Arguments

• bound - the bound value
• upper - true for an upper bound, false for a lower bound

pub fn upper_bound(upper_bound: f64) -> Self

Creates an upper-bound quota.

Arguments

• upper_bound - the highest acceptable value

Returns

The upper-bound quota.

pub fn lower_bound(lower_bound: f64) -> Self

Creates a lower-bound quota.

Arguments

• lower_bound - the lowest acceptable value

Returns

The lower-bound quota.

pub fn is_upper_bound(&self) -> bool

Returns whether this quota is an upper bound.

pub fn bound(&self) -> f64

Returns the bound value.

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

Returns whether the given value is acceptable under this quota.

Arguments

• value - the value to check against the bound

Trait Implementations

impl Clone for Quota

fn clone(&self) -> Quota

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Quota

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

Formats the value using the given formatter.

impl Display for Quota

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

Formats the value using the given formatter.

impl Hash for Quota

Hashes what PartialEq compares. Java hashes (int) bound, which would put 0.0 and -0.0, now unequal, under one hash; the Rust hash only has to agree with Rust’s equality, so it takes the bits.

fn hash<H: Hasher>(&self, state: &mut H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Quota

Java’s Quota.equals compares bound with the primitive ==, under which NaN differs from itself and 0.0 equals -0.0. A lawful Eq must be reflexive, so the bound is compared as Java’s Double.equals compares it instead: every NaN is equal, and the two zeros differ. Any other bound compares as in Java.

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
