Fields§

§content: Rc<RefCell<TypeVarContent>>

Implementations§

Get a fresh copy of self, named after name. Can only be called on non-derived typevars.

Returns the typeset for this TV. If the TV is derived, computes it recursively from the derived function and the base’s typeset. Note this can’t be done non-lazily in the constructor, because the TypeSet of the base may change over time.

Returns this typevar’s type set, assuming this type var has no parent.

If the associated typeset has a single type return it. Otherwise return None.

Get the free type variable controlling this one.

Create a type variable that is a function of another.

The resulting type after dereferencing.
Dereferences the value.
Feeds this value into the given Hasher. Read more

Converts this type into the (usually inferred) input type.
Converts this type into the (usually inferred) input type.
Converts this type into the (usually inferred) input type.
This method tests for self and other values to be equal, and is used by ==. Read more
This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason. Read more
