bitset

bitset

bitset -- persistent set of unsigned integers

Functions

create a string representation of a bitset of the form "{2, 4}"

redefines:

§
:
Any
 => 
Type 
[Inherited from  Any]
Get the dynamic type of this instance. For value instances `x`, this is
equal to `type_of x`, but for `x` with a `ref` type `x.dynamic_type` gives
the actual runtime type, while `type_of x` results in the static
compile-time type.

There is no dynamic type of a type instance since this would result in an
endless hierachy of types. So for Type values, dynamic_type is redefined
to just return Type.type.
§(bit u64)
:
Any
 => 
bool
test if the given bit is part of this bitset
get the highest bit in this bitset
alternative for has using []
is `this` contained in `Set` `s`?

This should usually be called using type inference as in

my_set := set_of ["A","B","C"]
say ("B" ∈ my_set)
say ("D" ∈ my_set)
is `this` not contained in `Set` `s`?

This should usually be called using type inference as in

my_set := set_of ["A","B","C"]
say ("B" ∉ my_set)
say ("D" ∉ my_set)
union of two bitsets
§
:
Any
 => 
String 
[Inherited from  Type]
name of this type, including type parameters, e.g. 'option (list i32)'.
§
:
Any
 => 
String 
[Inherited from  Any]
convenience prefix operator to create a string from a value.

This permits usage of `$` as a prefix operator in a similar way both
inside and outside of constant strings: $x and "$x" will produce the
same string.
set the given bit

Type Features

[Inherited from  Any]
Get a type as a value.

This is a feature with the effect equivalent to Fuzion's `expr.type` call tail.
It is recommended to use `expr.type` and not `expr.type_value`.

`type_value` is here to show how this can be implemented and to illustrate the
difference to `dynamic_type`.
monoid of bitset with infix ∪ operation.
