Enum GeometricError 

#[non_exhaustive]
pub enum GeometricError {
    ZeroMax,
    MaxTooLarge,
    InvalidProbability,
}

Errors that can occur when creating a Geometric level generator.

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.

ZeroMax

The maximum number of levels must be non-zero.

MaxTooLarge

The maximum number of levels must be less than i32::MAX.

InvalidProbability

The probability $q$ must be in the range $(0, 1)$.

Trait Implementations

impl Clone for GeometricError

fn clone(&self) -> GeometricError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for GeometricError

impl Debug for GeometricError

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

Formats the value using the given formatter.

impl Display for GeometricError

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

Formats the value using the given formatter.

impl Eq for GeometricError

impl Error for GeometricError

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 GeometricError

fn eq(&self, other: &GeometricError) -> 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.
