Enum ConversionError

pub enum ConversionError {
    IsNotLeapYear,
    TooManyDaysInMonth(u8),
    IsLeapYear,
    YearTooSmall,
}

Occurs when failing to get a Hebrew Date.

Variants

IsNotLeapYear

Occurs when attempting to get an Adar 1 or Adar 2 in a non-leap year.

Example:

let result = HebrewDate::from_ymd(5778,HebrewMonth::Adar1,NonZeroI8::new(1).unwrap());
assert!(!result.is_ok());
assert_eq!(result.unwrap_err(),ConversionError::IsNotLeapYear);

TooManyDaysInMonth(u8)

Occurs when trying to get a Hebrew Date who’s day is out of range

Example:

let result = HebrewDate::from_ymd(5778,HebrewMonth::Adar,NonZeroI8::new(40).unwrap());
assert!(!result.is_ok());
assert_eq!(result.unwrap_err(),ConversionError::TooManyDaysInMonth(29));

IsLeapYear

Occurs when attempting to get a regular Adar in a leap year.

Example:

let result = HebrewDate::from_ymd(5779,HebrewMonth::Adar,NonZeroI8::new(1).unwrap());
assert!(!result.is_ok());
assert_eq!(result.unwrap_err(),ConversionError::IsLeapYear);

YearTooSmall

Occurs when attempting to get a year that is before the epoch (currently: year 3764/4).

Example:

let result = HebrewDate::from_ymd(2448,HebrewMonth::Nissan,NonZeroI8::new(15).unwrap()); // What was the English day of the Exodus?
assert!(!result.is_ok());
assert_eq!(result.unwrap_err(),ConversionError::YearTooSmall);

Trait Implementations

impl Clone for ConversionError

fn clone(&self) -> ConversionError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ConversionError

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ConversionError

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for ConversionError

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

Formats the value using the given formatter.

impl Error for ConversionError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl PartialEq for ConversionError

fn eq(&self, other: &ConversionError) -> 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 ConversionError

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
