Struct RefTy

pub struct RefTy {
    pub pointee_ty: TyIdx,
}

The Ty of a reference (transparent pointer).

This is used to represent passing a value by-reference, and so backends should consider the “value” to be the pointee. If you want to test that a pointer doesn’t have its value corrupted but don’t care about the pointee, use PrimitiveTy::Ptr.

When used in the outputs of a Func, this expresses an out-param that the caller is responsible for “allocating” (and initializing?) and the callee is responsible for “writing” the value to it. The caller then checks the value just like other outputs.

Out-params should appear after “normal” inputs but before vararg inputs, with the name specified.

Trait Implementations

impl Clone for RefTy

fn clone(&self) -> RefTy

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RefTy

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

Formats the value using the given formatter.

impl Hash for RefTy

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for RefTy

fn eq(&self, other: &RefTy) -> 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.
