Implementations

impl Cardinality

pub fn is_valid(value: i32) -> bool

Returns true if value is a variant of Cardinality.

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

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

Trait Implementations

impl Clone for Cardinality

fn clone(&self) -> Cardinality

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Cardinality

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

Formats the value using the given formatter.

impl Default for Cardinality

fn default() -> Cardinality

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Cardinality

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error> where

impl Ord for Cardinality

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

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

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