Struct Objective 

pub struct Objective(/* private fields */);

A reliability target, stored as a ratio in the open interval (0, 1).

99.9% availability is Objective::percent(99.9) and reads back as a ratio of 0.999.

Implementations

impl Objective

pub fn percent(p: f64) -> Result<Self>

Build an objective from a percentage in the open interval (0, 100).

pub fn ratio(r: f64) -> Result<Self>

Build an objective from a ratio in the open interval (0, 1).

pub fn as_ratio(&self) -> f64

The objective as a ratio, e.g. 0.999.

pub fn as_percent(&self) -> f64

The objective as a percentage, e.g. 99.9.

pub fn error_budget_ratio(&self) -> f64

The error-budget ratio, i.e. 1 - objective.

Trait Implementations

impl Clone for Objective

fn clone(&self) -> Objective

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Objective

impl Debug for Objective

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

Formats the value using the given formatter.

impl PartialEq for Objective

fn eq(&self, other: &Objective) -> 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.
