Enum Certainty 

#[repr(u8)]
pub enum Certainty {
    Definite = 0,
    Approximate = 1,
    Uncertain = 2,
    Unknown = 3,
}

Epistemic certainty of a BTIC bound value.

Certainty is metadata only; it does not affect comparison or ordering.

Variants

Definite = 0

Bound is known precisely to stated granularity.

Approximate = 1

Bound is estimated; true value may differ by +/-1 unit of granularity.

Uncertain = 2

Bound is weakly estimated; true value may differ significantly.

Unknown = 3

Bound is not meaningfully known; stored value is a best guess.

Implementations

impl Certainty

pub fn from_code(code: u8) -> Result<Self, BticError>

Construct from a 2-bit code (0b00..=0b11).

pub fn code(self) -> u8

The numeric code for this certainty level.

pub fn name(self) -> &'static str

Human-readable name.

pub fn least_certain(self, other: Self) -> Self

Returns the least certain of two values (max of the codes).

Trait Implementations

impl Clone for Certainty

fn clone(&self) -> Certainty

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Certainty

impl Debug for Certainty

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

Formats the value using the given formatter.

impl Display for Certainty

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

Formats the value using the given formatter.

impl Eq for Certainty

impl Hash for Certainty

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 Ord for Certainty

fn cmp(&self, other: &Certainty) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Certainty

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

impl PartialOrd for Certainty

fn partial_cmp(&self, other: &Certainty) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
