import { id } from "https://deno.land/x/denops_std@v6.5.0/function/nvim/mod.ts";
Returns a String
which is a unique identifier of the
container type (List
, Dict
, Blob
and Partial
). It is
guaranteed that for the mentioned types id(v1) ==# id(v2)
returns true iff type(v1) == type(v2) && v1 is v2
.
Note that v:_null_string
, v:_null_list
, v:_null_dict
and
v:_null_blob
have the same id()
with different types
because they are internally represented as NULL pointers.
id()
returns a hexadecimal representanion of the pointers to
the containers (i.e. like 0x994a40
), same as printf("%p", {expr})
, but it is advised against counting on the exact
format of the return value.
It is not guaranteed that id(no_longer_existing_container)
will not be equal to some other id()
: new containers may
reuse identifiers of the garbage-collected ones.
