Input: ll · Output: result

What it is

ll is a linked_list handle.

Overloads

One call shape — this function is not overloaded.

Code	Input	Output	Description
`result = to_vec(ll)`	`ll` Listnot documented yet	`result` List	Returns a `List`: the linked list's elements, front to back.

Examples

From the documentation, and run by the build -- the output and the figure below are what the engine actually produced. Simplest first.

l = linked_list()
l.push_back(1)
l.push_back(2)
l.push_front(0)
print(l.to_vec())   # (0, 1, 2)

print(pop_front(l)) # 0 -- removes from the front

print(pop_back(l))  # 2 -- removes from the back

print(l.to_vec())   # (1) -- what's left

output

(0, 1, 2)
0
2
(1)

How it works

linked_list() (§ data structures pass, 2026-09-01, that module's own doc comment for why VecDeque rather than a real boxed-node chain.

From the note above this builtin in the interpreter, where the reasoning was written down as it was built.
