Enum ValidityKind

#[repr(i32)]
pub enum ValidityKind {
    Good = 0,
    Invalid = 1,
    Reserved = 2,
    Questionable = 3,
}

Validity of the value, as condensed information for the client. In case this value is not ‘good’, some reasons may be found in the ‘detailQual’.

Variants

Good = 0

Supervision function has detected no abnormal condition of either the acquisition function or the information source.

Invalid = 1

Supervision function has detected an abnormal condition of the acquisition function or the information source (missing or non-operating updating devices). The value is not defined under this condition. It shall be used to indicate to the client that the value may be incorrect and shall not be used. EXAMPLE If an input unit detects an oscillation of one input it will mark the related information as invalid.

Reserved = 2

Reserved

Questionable = 3

Supervision function has detected any abnormal behaviour. However, the value could still be valid. It is client’s responsibility to determine whether the values should be used.

Implementations

impl ValidityKind

pub fn is_valid(value: i32) -> bool

Returns true if value is a variant of ValidityKind.

pub fn from_i32(value: i32) -> Option<ValidityKind>

Converts an i32 to a ValidityKind, or None if value is not a valid variant.

Trait Implementations

impl Clone for ValidityKind

fn clone(&self) -> ValidityKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ValidityKind

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

Formats the value using the given formatter.

impl Default for ValidityKind

fn default() -> ValidityKind

Returns the “default value” for a type.

impl From<ValidityKind> for i32

fn from(value: ValidityKind) -> i32

Converts to this type from the input type.

impl Hash for ValidityKind

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 ValidityKind

fn cmp(&self, other: &ValidityKind) -> 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 ValidityKind

fn eq(&self, other: &ValidityKind) -> 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 ValidityKind

fn partial_cmp(&self, other: &ValidityKind) -> 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.
