Enum PtrType 

pub enum PtrType {
    Ref {
        mutbl: Mutability,
        pointee: PointeeInfo,
    },
    Box {
        pointee: PointeeInfo,
    },
    Raw {
        meta_kind: PointerMetaKind,
    },
    FnPtr,
    VTablePtr(TraitName),
}

Stores all the information that we need to know about a pointer.

Variants

Ref

Fields

mutbl: Mutability

Indicates a shared vs mutable reference.

pointee: PointeeInfo

Describes what we know about the pointee.

Box

Fields

pointee: PointeeInfo

Raw

Fields

meta_kind: PointerMetaKind

Indicates what kind of metadata this pointer carries.

FnPtr

VTablePtr(TraitName)

This is a “stand-alone” vtable pointer, something that does not exist in surface Rust.

Implementations

impl PtrType

pub fn as_wide_pair<T>(self) -> Option<Type>

where T: Target + Obj,

Returns a pair type representing this wide pointer or None if it is thin.

impl PtrType

pub fn safe_pointee(self) -> Option<PointeeInfo>

If this is a safe pointer, return the pointee information.

pub fn meta_kind(self) -> PointerMetaKind
