Enum NotationError 

#[non_exhaustive]
pub enum NotationError {
    InvalidFormat,
    InvalidNumber(ParseIntError),
    Zero(&'static str),
    InvalidOperator,
    NumberTooLarge(u32),
}

An error from parsing or constructing dice notation.

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.

InvalidFormat

The input doesn’t match the XdY?Z notation format.

InvalidNumber(ParseIntError)

A number in the input couldn’t be parsed, usually because it’s too large for a u32.

Zero(&'static str)

A value that must be positive was zero. Holds the name of the value: "count", "sides" or "divisor".

InvalidOperator

The operator isn’t one of +, -, * or /.

NumberTooLarge(u32)

A value exceeded the maximum. Holds the maximum, MAX_VALUE.

Trait Implementations

impl Debug for NotationError

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

Formats the value using the given formatter.

impl Display for NotationError

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

Formats the value using the given formatter.

impl Error for NotationError

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 From<ParseIntError> for NotationError

fn from(source: ParseIntError) -> Self

Converts to this type from the input type.

impl PartialEq for NotationError

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

Equality operator ==.

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

Inequality operator !=.
