Struct Class 

pub struct Class { /* private fields */ }

A builtin exception class, as a value.

This is what the name ValueError is bound to. Calling it makes an Exception, which is the only thing it does, and which is why it holds nothing but the Kind it constructs.

Implementations

impl Class

pub const fn new(kind: Kind) -> Self

The class for this kind.

pub const fn kind(self) -> Kind

Which class it is.

pub fn instance(self, args: Vec<Object>) -> Object

An instance of it, which is what calling the class does.

Trait Implementations

impl Clone for Class

fn clone(&self) -> Class

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Class

impl Debug for Class

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

Formats the value using the given formatter.

impl Eq for Class

impl Native for Class

fn type_name(&self) -> &str

The type of a class is type, the same as for every other class.

fn repr(&self) -> String

What repr prints.

fn as_any(&self) -> &dyn Any

The concrete value, for the runtime to downcast back to.

fn display(&self) -> String

What str prints, which for a type with no __str__ of its own is whatever repr prints. Almost every native type wants the default. An exception is the one that does not, because str(e) is the message and repr(e) is the call that would make it again.

fn truthy(&self) -> bool

Python’s truth protocol, which for an object with no __bool__ and no __len__ is true. Almost every native type wants the default.

fn walking(&self) -> bool

Whether this is already an iterator, meaning iter(x) is x and a for over a half consumed one carries on rather than starting again.

fn equals(&self, _other: &dyn Native) -> bool

Whether this is equal to another native value that is not the same object as it.

fn hash(&self) -> Option<i64>

This value’s hash, or nothing to be hashed by address like an object with no __hash__ of its own.

impl PartialEq for Class

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

Equality operator ==.

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

Inequality operator !=.
