type ('a, 'b) t = ('a * 'b) list
val get : eq:('a -> 'a -> bool) -> 'a -> ('a, 'b) t -> 'b option
Find the element.
val get_exn : eq:('a -> 'a -> bool) -> 'a -> ('a, 'b) t -> 'b
Like get, but unsafe.
get
Not_found
if the element is not present.
val set : eq:('a -> 'a -> bool) -> 'a -> 'b -> ('a, 'b) t -> ('a, 'b) t
Add the binding into the list (erase it if already present).
val mem : eq:('a -> 'a -> bool) -> 'a -> ('a, _) t -> bool
mem x l returns true iff x is a key in l.
mem x l
true
x
l
val update : eq:('a -> 'a -> bool) -> f:('b option -> 'b option) -> 'a -> ('a, 'b) t -> ('a, 'b) t
update k ~f l updates l on the key k, by calling f (get l k) and removing k if it returns None, mapping k to v' if it returns Some v'.
update k ~f l
k
f (get l k)
None
v'
Some v'
val remove : eq:('a -> 'a -> bool) -> 'a -> ('a, 'b) t -> ('a, 'b) t
remove x l removes the first occurrence of k from l.
remove x l
