@documents Hashtbl.Cap

type ('a, 'b, 'c) t constraint 'c = [< `Read | `Write ]

The type of a hashtable.

Constructors
val create : int -> ('a, 'b, _) t
val of_table : ('a, 'b) Hashtbl.t -> ('a, 'b, _) t

Adopt a regular hashtable as a capability hashtble, allowing to decrease capabilities if necessary.

This operation involves no copying. In other words, in let cap = of_table a in ..., any modification in a will also have effect on cap and reciprocally.

val to_table : ('a, 'b, [ `Read | `Write ]) t -> ('a, 'b) Hashtbl.t

Return a capability hashtable as a regular hashtable.

This operation requires both read and write permissions on the capability table and involves no copying. In other words, in let a = of_table cap in ..., any modification in a will also have effect on cap and reciprocally.

val read_only : ('a, 'b, [> `Read ]) t -> ('a, 'b, [ `Read ]) t

Drop to read-only permissions.

This operation involves no copying.

val write_only : ('a, 'b, [> `Write ]) t -> ('a, 'b, [ `Write ]) t

Drop to write-only permissions.

This operation involves no copying.
