    FirstQuarter,
    WaxingGibbous,
    FullMoon,

Implementations

impl Phase

pub fn as_emoji(self) -> char

Returns the Unicode emoji representation of the moon phase.

assert_eq!(Phase::FullMoon.as_emoji(), '🌕');

pub fn iter() -> Iter<'static, Phase>

Views the eight moon phases as an iterator.

assert_eq!(Phase::iter().next(), Some(&Phase::NewMoon));
assert_eq!(Phase::iter().len(), 8);

pub fn is_principal(self) -> bool

Returns true if the phase is one of the four principal phases.

assert_eq!(Phase::NewMoon.is_principal(), true);

Trait Implementations

impl Clone for Phase

fn clone(&self) -> Phase

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Phase

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

Formats the value using the given formatter.

impl From<PrincipalPhase> for Phase

fn from(phase: PrincipalPhase) -> Phase

Converts to this type from the input type.

impl Hash for Phase

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 Phase

fn eq(&self, other: &Phase) -> 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 Copy for Phase

impl Eq for Phase

impl StructuralPartialEq for Phase
