Enum ValidationError 

pub enum ValidationError {
    InvalidDate {
        rule: &'static str,
    },
    OutOfRange {
        what: &'static str,
    },
}

Error returned when an input cannot be accepted as a valid date or when a value falls outside the range a convention accepts.

The crate has a single error type because every failure mode reduces to one of two shapes: an input that does not name a real date, or an input that is well-formed in isolation but outside the supported range.

Examples

use regit_daycount::errors::ValidationError;

let err = ValidationError::InvalidDate { rule: "day-out-of-range" };
assert_eq!(err, ValidationError::InvalidDate { rule: "day-out-of-range" });

Variants

InvalidDate

The (year, month, day) triple does not name a real Gregorian date; rule names the violated structural rule.

Fields

rule: &'static str

A short, human-readable description of the violated rule.

OutOfRange

A value is well-formed in isolation but falls outside the range the caller’s convention or calendar accepts; what names the value.

Fields

what: &'static str

A short, human-readable description of the out-of-range value.

Trait Implementations

impl Eq for ValidationError

impl Error for ValidationError

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 ValidationError

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

Equality operator ==.

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

Inequality operator !=.
