the mutate effect

element type

add an element at the end of this Dynamic_Array

amortized O(1) but worst case of O(n)

iteratively add all element at the end of this Dynamic_Array

convert this buffer to an immutable array

create immutable array from this taking at most max_length elements

create a list from this Dynamic_Array

string representation of this buffer's contents

can another element be added to the end of this Dynamic_Array?

True if either the internal data structure has space
for another element or this Dynamic_Array is able to grow

does this array contain elem?

dynamic_apply -- apply `f.call` to `Any.this`'s dynamic type and value

This can be used to perform operation on values depending on their dynamic
type.

Here is an example that takes a `Sequence Any` that may contain boxed values
of types `i32` and `f64`. We can now write a feature `get_f64` that extracts
these values converted to `f64` and build a function `sum` that sums them up
as follows:

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 hierarchy of types. So for Type values, dynamic_type is redefined
to just return Type.type.

get element at given index i

set element at given index i to given value o

a sequence of all valid indices to access this array. Useful e.g., for
`for`-loops:

A buffer might be inaccessible, e.g. because it is a shared mutate.array that
is not accessible by the current thread.

is this empty?

length of this array, i.e. number of actual elements, NOT the length of the internal array

the maximum length this array can grow to in case it is limited

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.

remove the last element of the this Dynamic_Array

amortized O(1) but worst case of O(n)

string representation of this type to be used for debugging.

result has the form "Type of '<name>'", but this might change in the future

There is no dynamic type of a type instance since this would result in an
endless hierarchy of types, so dynamic_type is redefined to just return
Type.type here.

initialize an empty Fixed_Capacity_Array of type T with default capacity of `min_length`

initialize an empty Fixed_Capacity_Array of type T with the given capacity

initialize a Fixed_Capacity_Array from a Sequence, capacity is set to the length of the Sequence

Is this type assignable to a type parameter with constraint `T`?

The result of this is a compile-time constant that can be used to specialize
code for a particular type.


it is most useful in conjunction with preconditions or `if` statements as in


or

the length below which the internal array won't shrink

name of this type, including type parameters, e.g. 'option (list i32)'.

initialize a Fixed_Capacity_Array

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.

NYI: Redefinition allows the type feature to be distinguished from its normal counterpart, see #3913

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`.
