Enum RateError 

#[non_exhaustive]
pub enum RateError {
    NoSolution,
    MultipleSolutions,
    BudgetExceeded,
    Unrated,
    UnsupportedVersion(u32),
}

An error from rating a puzzle.

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.

NoSolution

The puzzle has no solution.

MultipleSolutions

The puzzle has more than one solution.

BudgetExceeded

The work budget ran out.

Unrated

The supported human techniques could not complete a unique puzzle.

UnsupportedVersion(u32)

A requested historical algorithm is retired or unavailable.

impl Eq for RateError

impl Error for RateError

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
