Enum NextError 

#[non_exhaustive]
pub enum NextError {
    NoCalendarChange,
    NegativeYearValue {
        year: i32,
    },
    SemLevelNotInFormat {
        spec: String,
    },
    NewDateIsBefore,
}

An error that occurred while incrementing a Version.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

NoCalendarChange

When updating a Cal version, the date provided yielded an identical version.

NegativeYearValue

When updating a Cal or CalSem version, the date year was negative.

Fields

year: i32

The year value

SemLevelNotInFormat

When updating/incrementing a Sem or CalSem version, the semantic level is not in the format.

Fields

spec: String

The semantic specifier

NewDateIsBefore

The new date passed to a next call was before the date represented by the current version.

Trait Implementations

impl Debug for NextError

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

Formats the value using the given formatter.

impl Display for NextError

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

Formats the value using the given formatter.

impl Error for NextError

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 From<NextError> for CompositeError

fn from(source: NextError) -> Self

Converts to this type from the input type.

impl PartialEq for NextError

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