Enum TypeError 

pub enum TypeError {
    InvalidDate {
        year: i32,
        month: u32,
        day: u32,
    },
    NonPositiveRange,
    NonFinite {
        name: &'static str,
    },
    InvalidTenor {
        reason: &'static str,
    },
}

Error returned when constructing or querying a basic numeric / temporal type (Date, Tenor, Daycount).

Examples

use regit_curves::errors::TypeError;

let err = TypeError::InvalidDate { year: 2023, month: 2, day: 30 };
assert_eq!(
    format!("{err}"),
    "invalid calendar date: 2023-02-30",
);

Variants

InvalidDate

Date::from_ymd received an invalid calendar date (out-of-range month/day, or a day that does not exist in the given month — e.g. February 30).

Fields

year: i32

The supplied year.

month: u32

The supplied month.

day: u32

The supplied day.

NonPositiveRange

A non-positive day count was requested where a positive value is required (e.g. day-count year fraction across a zero or negative range, or a degenerate compounding t <= 0 for rate_from_discount).

NonFinite

A non-finite (NaN or infinite) number was supplied where a finite value is required.

Fields

name: &'static str

Human-readable name of the offending input.

InvalidTenor

A frequency or tenor count is invalid (zero, negative for a unit that requires positive, or otherwise out of range — including Daycount::Business252 queried without a calendar).

Fields

reason: &'static str

Human-readable reason.

Trait Implementations

impl Clone for TypeError

fn clone(&self) -> TypeError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for TypeError

impl Debug for TypeError

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

Formats the value using the given formatter.

impl Display for TypeError

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

Formats the value using the given formatter.

impl Eq for TypeError

impl Error for TypeError

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<TypeError> for CurveError

fn from(e: TypeError) -> Self

Converts to this type from the input type.

impl From<TypeError> for BootstrapError

fn from(e: TypeError) -> Self

Converts to this type from the input type.

impl Hash for TypeError

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 TypeError

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

Equality operator ==.
