Enum PrincipalPhase

pub enum PrincipalPhase {
    NewMoon,
    FirstQuarter,
    FullMoon,
    LastQuarter,
}

The four principal phases of the Moon.

Variants

NewMoon

🌑 The Moon appears completely dark.

FirstQuarter

🌓 The Moon is half visible after the new moon and before the full moon.

FullMoon

🌕 The Moon is fully visible.

LastQuarter

🌗 The Moon is half visible after the full moon and before the new moon.

Implementations

impl PrincipalPhase

pub fn as_emoji(self) -> char

Returns the Unicode emoji representation of the moon phase.

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

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

Views the four principal moon phases as an iterator.

assert_eq!(PrincipalPhase::iter().next(), Some(&PrincipalPhase::NewMoon));
assert_eq!(PrincipalPhase::iter().len(), 4);

Trait Implementations

impl Clone for PrincipalPhase

fn clone(&self) -> PrincipalPhase

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PrincipalPhase

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 PrincipalPhase

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 PrincipalPhase

fn eq(&self, other: &PrincipalPhase) -> 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.
