assert_eq!(Month::January.previous(), Month::December);

pub const fn next(self) -> Self

Get the next month.

assert_eq!(Month::January.next(), Month::February);

pub const fn nth_next(self, n: u8) -> Self

Trait Implementations

impl Arbitrary for Month

fn arbitrary(g: &mut Gen) -> Self

Return an arbitrary value.

fn shrink(&self) -> Box<dyn Iterator<Item = Self>>

Return an iterator of values that are smaller than itself.

impl Clone for Month

fn clone(&self) -> Month

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Month

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

Formats the value using the given formatter.

impl<'a> Deserialize<'a> for Month

fn deserialize<D: Deserializer<'a>>(deserializer: D) -> Result<Self, D::Error>

Deserialize this value from the given Serde deserializer.

#[doc(hidden)] fn deserialize_in_place<D>( deserializer: D, place: &mut Self, ) -> Result<(), <D as Deserializer<'de>>::Error>

where D: Deserializer<'de>,

Deserializes a value into self from the given Deserializer.

impl Display for Month

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

Formats the value using the given formatter.

impl Distribution<Month> for Standard

fn sample<R: Rng + ?Sized>(&self, rng: &mut R) -> Month

Generate a random value of T, using rng as the source of randomness.

fn sample_iter<R>(self, rng: R) -> DistIter<Self, R, T>

where R: Rng, Self: Sized,

Create an iterator that generates random values of T, using rng as the source of randomness.

fn map<F, S>(self, func: F) -> DistMap<Self, F, T, S>

where F: Fn(T) -> S, Self: Sized,

Create a distribution of values of ‘S’ by mapping the output of Self through the closure F

impl Eq for Month

#[doc(hidden)] fn assert_receiver_is_total_eq(&self)

impl From<Month> for u8

fn from(month: Month) -> Self

Converts to this type from the input type.

impl FromStr for Month

type Err = InvalidVariant

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl Hash for Month

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 PartialEq for Month

fn eq(&self, other: &Month) -> 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 Serialize for Month

fn serialize<S: Serializer>(&self, serializer: S) -> Result<S::Ok, S::Error>

Serialize this value into the given Serde serializer.

impl SmartDisplay for Month

type Metadata = MonthMetadata

User-provided metadata type.

fn metadata(&self, _: FormatterOptions) -> Metadata<'_, Self>

Compute any information needed to format the value. This must, at a minimum, determine the width of the value before any padding is added by the formatter.

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

Format the value using the given formatter. This is the same as Display::fmt.

fn fmt_with_metadata( &self, f: &mut Formatter<'_>, _metadata: Metadata<'_, Self>, ) -> Result<(), Error>

Format the value using the given formatter and metadata. The formatted output should have the width indicated by the metadata. This is before any padding is added by the formatter.

impl TryFrom<u8> for Month

type Error = ComponentRange

The type returned in the event of a conversion error.

fn try_from(value: u8) -> Result<Self, Self::Error>

Performs the conversion.

impl Copy for Month
