Implementations

impl Month

pub const fn length(self, year: i32) -> u8

Get the number of days in the month of a given year.

assert_eq!(Month::February.length(2020), 29);

pub const fn previous(self) -> Month

Get the previous month.

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

pub const fn next(self) -> Month

Get the next month.

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

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

Get n-th next month.

assert_eq!(Month::January.nth_next(4), Month::May);
assert_eq!(Month::July.nth_next(9), Month::April);

pub const fn nth_prev(self, n: u8) -> Month

Get n-th previous month.

assert_eq!(Month::January.nth_prev(4), Month::September);
assert_eq!(Month::July.nth_prev(9), Month::October);

Trait Implementations

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<(), Error>

Formats the value using the given formatter.

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

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

where D: Deserializer<'a>,

Deserialize this value from the given Serde deserializer.

impl Display for Month

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

Formats the value using the given formatter.

impl FromStr for Month

type Err = InvalidVariant

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Month, <Month as FromStr>::Err>

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

impl Hash for Month

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

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

where S: Serializer,

Serialize this value into the given Serde serializer.

impl SmartDisplay for Month

type Metadata = MonthMetadata

User-provided metadata type.

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

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<(), Error>

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<Month, <Month as TryFrom<u8>>::Error>

Performs the conversion.
