Implementations

impl DatumType

pub fn is_valid(value: i32) -> bool

Returns true if value is a variant of DatumType.

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

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

impl Ord for DatumType

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

This method returns an Ordering between self and other.

#[must_use]pub fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

#[must_use]pub fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

#[must_use]pub fn clamp(self, min: Self, max: Self) -> Self

Restrict a value to a certain interval.

impl PartialEq<DatumType> for DatumType

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

This method tests for self and other values to be equal, and is used by ==.

#[must_use]pub fn ne(&self, other: &Rhs) -> bool

This method tests for !=.

impl PartialOrd<DatumType> for DatumType

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