[−][src]Macro ocaml_interop::to_ocaml
Converts Rust values into OCaml values.
In to_ocaml!(cr, value)
, cr
is an OCaml Runtime handle, and value
is
a Rust value of a type that implements the ToOCaml
trait. The resulting
value's lifetime is bound to cr
's borrow.
An alternative form accepts a third "root variable" argument: to_ocaml!(cr, value, rootvar)
.
rootvar
is one of the "root variables" declared when opening an ocaml_frame!
.
This variant consumes rootvar
returns an OCamlRef
value instead of an OCaml
one.
Examples
let ocaml_string: OCaml<String> = to_ocaml!(cr, "hello OCaml!"); // ...
Variant:
ocaml_frame!(cr, (rootvar), { let ocaml_string_ref: OCamlRef<String> = to_ocaml!(cr, "hello OCaml!", rootvar); // ... });
