Enum Error 

#[non_exhaustive]
pub enum Error {
    ParseCoord(String),
    OutOfRange {
        what: &'static str,
        value: f64,
    },
    InvalidOptics(String),
}

Everything that can go wrong constructing target-match values.

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.

ParseCoord(String)

A coordinate string could not be parsed (empty, non-numeric, malformed sexagesimal, or negative minutes/seconds).

OutOfRange

A numeric coordinate or epoch was outside its valid domain (RA [0, 360), Dec [-90, 90], or a non-finite epoch year).

Fields

what: &'static str

Which quantity was out of range (e.g. "right ascension").

value: f64

The offending value.

InvalidOptics(String)

Optics or field inputs were non-positive, non-finite, or insufficient to derive a field of view.

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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 Error

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

Equality operator ==.

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

Inequality operator !=.
