Enum InvalidFpFunctor 

pub enum InvalidFpFunctor {
    ObGen(QualifiedName),
    MorGen(QualifiedName),
    Dom(QualifiedName),
    Cod(QualifiedName),
    Eq(QualifiedName),
}

A failure of a map out of an f.p. category to be functorial.

Variants

ObGen(QualifiedName)

An object generator not mapped to an object in the codomain category.

MorGen(QualifiedName)

A morphism generator not mapped to a morphism in the codomain category.

Dom(QualifiedName)

A morphism generator whose domain is not preserved.

Cod(QualifiedName)

A morphism generator whose codomain is not preserved.

Eq(QualifiedName)

A path equation in domain presentation that is not respected.

Trait Implementations

impl Debug for InvalidFpFunctor

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

Formats the value using the given formatter.

impl Display for InvalidFpFunctor

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

Formats the value using the given formatter.

impl Error for InvalidFpFunctor

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 InvalidFpFunctor

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