👎Deprecated:

To improve API stability with ruby-head, direct usage of Ruby internal structs has been deprecated. To migrate, please replace the usage of this internal struct with its counterpart in the rb_sys::stable module. For example, instead of use rb_sys::rb_sys__Opaque__ExampleStruct;, use use rb_sys::stable::ExampleStruct;. If you need to access the internals of these items, you can use the provided rb-sys::macros instead.

“Typed” user data. By using this, extension libraries can wrap a C struct to make it visible from Ruby. For instance if you have a struct timeval, and you want users to use it,

static inline const [`rb_data_type_t`] timeval_type = {
    // Note that unspecified fields are 0-filled by default.
    .wrap_struct_name = "timeval",
    .function = {
        .dmark = nullptr,                 // no need to mark
        .dfree = RUBY_TYPED_DEFAULT_FREE, // use ruby_xfree()
        .dsize = [](auto) {
            return sizeof(struct timeval);
        },
    },
};

extern "C" void
Init_timeval(void)
{
    auto klass = [`rb_define_class`]"YourName", [`rb_cObject`];

    [`rb_define_alloc_func`]klass, [](auto klass) {
        struct timeval *t;
        auto ret = TypedData_Make_Struct(
           klass, struct timeval, &timeval_type, t);

        if (auto i = gettimeofday(t, nullptr); i == -1) {
            [`rb_sys_fail`]"gettimeofday(3)");
        }
        else {
            return ret;
        }
    });
}

This field stores various information about how Ruby should handle a data. This roughly resembles a Ruby level class (apart from method definition etc.)

This has to be always 1.

@internal

Why, then, this is not a const ::VALUE?

Trait Implementations

impl Clone for RTypedData

fn clone(&self) -> RTypedData

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for RTypedData

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for RTypedData

fn eq(&self, other: &RTypedData) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
