Enum heca_lib::prelude::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 copy of the value.

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

Performs copy-assignment from source.

impl Copy for ConversionError

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 Eq for ConversionError

impl Error for ConversionError

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

The lower-level source of this error, if any.

fn backtrace(&self) -> Option<&Backtrace>

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

Returns a stack backtrace, if available, of where this error occurred.

fn description(&self) -> &str

👎 Deprecated since 1.42.0:

use the Display impl or to_string()

if let Err(e) = "xc".parse::<u32>() { // Print e itself, no need for description(). eprintln!("Error: {}", e); }

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

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

impl PartialEq<ConversionError> for ConversionError

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

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &ConversionError) -> bool

This method tests for !=.

impl Serialize for ConversionError

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