Enum Error 

#[non_exhaustive]
pub enum Error<O: Copy + Debug> {
    FromNone,
    Other(O),
}

RRTK follows the enum style of error handling. This is the error type returned from nearly all RRTK types, but you can add your own custom error type using Other(O). It is strongly recommended that you use a single O type across your crate.

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.

FromNone

Returned when a None is elevated to an error by a NoneToError.

Other(O)

A custom error of a user-defined type. Not created by any RRTK type but can be propagated by them.

Trait Implementations

impl<O: Clone + Copy + Debug> Clone for Error<O>

fn clone(&self) -> Error<O>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<O: Debug + Copy + Debug> Debug for Error<O>

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

Formats the value using the given formatter.

impl<O: PartialEq + Copy + Debug> PartialEq for Error<O>

fn eq(&self, other: &Error<O>) -> 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.
