Enum InvalidFunction

pub enum InvalidFunction<T> {
    Dom(T),
    Cod(T),
}

A failure of a mapping to restrict to a function between two sets.

Variants

Dom(T)

The mapping is not defined at a point in the domain.

Cod(T)

The image of a point in the domain is not contained in the codomain.

Trait Implementations

impl<T: Debug> Debug for InvalidFunction<T>

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

Formats the value using the given formatter.

impl<T> Display for InvalidFunction<T>

where T: Display,

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

Formats the value using the given formatter.

impl<T> Error for InvalidFunction<T>

where Self: Debug + Display,

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<T: PartialEq> PartialEq for InvalidFunction<T>

fn eq(&self, other: &InvalidFunction<T>) -> 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.
