val stable_dedup : 'a t -> 'a t
stable_dedup
Same asdedup
but maintains the order of the list and doesn't allow compare function to be specified (otherwise, the implementation in terms of Set.t would hide a heavyweight functor instantiation at each call).
val stable_dedup_staged : compare:('a -> 'a -> Core_kernel__.Import.int) -> ('a Core_kernel__.Import.list -> 'a Core_kernel__.Import.list) Core_kernel__.Import.Staged.t
exception
Duplicate_found of Core_kernel__.Import.unit -> Base.Sexp.t * Core_kernel__.Import.string
Only raised in
exn_if_dup
below.

exn_if_dup ~compare ?context t ~to_sexp
raises ift
contains a duplicate. It will specifically raise aDuplicate_found
exception and usecontext
as its second argument. O(n log n) time complexity.
val slice : 'a t -> Core_kernel__.Import.int -> Core_kernel__.Import.int -> 'a t
slice t start stop
returns a new list including elementst.(start)
throught.(stop-1)
, normalized Python-style with the exception thatstop = 0
is treated asstop = length t
.

Like

Randomly drops elements from the input list. Length is chosen uniformly between 0 and the length of the input, inclusive.

zip_with_remainder xs ys
zips as many elements as possible ofxs
andys
together and also returns the un-zipped remainder of the longer input, if the inputs have different lengths.If
xs
andys
have the same length,zip_with_remainder xs ys
returns the same thing as(zip_exn xs ys, None)
