Class type
A lock-free thread-safe int
eger keyed hash table.
This is designed for associating thread specific state with threads within a domain.
⚠️ This is not parallelism-safe — only thread-safe within a single domain.
val create : unit -> 'v t
create ()
returns a new lock-free thread-safe int
eger keyed hash table. The hash table is automatically resized.
val length : 'v t -> int
length t
returns the number of bindings in the hash table t
.
⚠️ The returned value may be greater than the number of distinct keys in the hash table.
val find : 'v t -> int -> 'v
find t k
returns the current binding of k
in hash table t
, or raises Not_found
if no such binding exists.
⚠️ This may use raise_notrace
for performance reasons.
val add : 'v t -> int -> 'v -> unit
add t k v
adds a binding of key k
to value v
to the hash table shadowing the previous binding of the key k
, if any.
val remove : 'v t -> int -> unit
remove t k
removes the most recent existing binding of key k
, if any, from the hash table t
thereby revealing the earlier binding of k
, if any.
