Enum CatalanError 

pub enum CatalanError {
    ZeroOrder,
    CatalanOverflow(u64),
    FussCatalanOverflow {
        order: u64,
        n: u64,
    },
}

Errors returned by checked Catalan-family helpers.

Variants

ZeroOrder

The Fuss-Catalan order must be at least one.

CatalanOverflow(u64)

The Catalan number no longer fits in u128.

FussCatalanOverflow

The Fuss-Catalan number no longer fits in u128.

Fields

order: u64

The requested Fuss-Catalan order.

n: u64

The requested sequence index.

Trait Implementations

impl Clone for CatalanError

fn clone(&self) -> CatalanError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CatalanError

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

Formats the value using the given formatter.

impl Display for CatalanError

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

Formats the value using the given formatter.

impl Error for CatalanError

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 CatalanError

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