# lwt-dllist - Mutable doubly-linked list
|
|
|
|
An `Lwt_dllist` is an object holding a list of elements which support
|
|
the following operations:
|
|
|
|
- adding an element to the left or the right in time and space O(1)
|
|
- taking an element from the left or the right in time and space O(1)
|
|
- removing a previously added element from a sequence in time and space O(1)
|
|
- removing an element while the sequence is being traversed.
|
|
|
|
## History
|
|
|
|
This module was formerly part of the Lwt core distribution as the
|
|
`Lwt_sequence` module, but has been pulled out into a separate library since it
|
|
is really just an implementation detail of Lwt.
|
|
|
|
You can migrate existing uses of `Lwt_sequence` into `Lwt_dllist` by simply
|
|
renaming the module. The implementation of the module remains unchanged, but
|
|
the name reflects the fact that the implementation is a doubly-linked list.
