Struct PointerDef

#[repr(C)]
pub struct PointerDef<'shape> {
    pub vtable: &'shape PointerVTable<'shape>,
    pub pointee: Option<fn() -> &'shape Shape<'shape>>,
    pub weak: Option<fn() -> &'shape Shape<'shape>>,
    pub strong: Option<fn() -> &'shape Shape<'shape>>,
    pub flags: PointerFlags,
    pub known: Option<KnownPointer>,
}

Describes a pointer — including a vtable to query and alter its state, and the inner shape (the pointee type in the pointer).

Fields

vtable: &'shape PointerVTable<'shape>

vtable for interacting with the pointer

pointee: Option<fn() -> &'shape Shape<'shape>>

shape of the inner type of the pointer, if not opaque

weak: Option<fn() -> &'shape Shape<'shape>>

shape of the corresponding strong pointer, if this pointer is weak

strong: Option<fn() -> &'shape Shape<'shape>>

shape of the corresponding weak pointer, if this pointer is strong

flags: PointerFlags

Flags representing various characteristics of the pointer

known: Option<KnownPointer>

An optional field to identify the kind of pointer

Implementations

impl<'shape> PointerDef<'shape>

pub const fn builder() -> PointerDefBuilder<'shape>

Creates a new PointerDefBuilder with all fields set to None.

pub fn pointee(&self) -> Option<&'shape Shape<'shape>>

Returns shape of the inner type of the pointer, if not opaque

pub fn weak(&self) -> Option<&'shape Shape<'shape>>

Returns shape of the corresponding strong pointer, if this pointer is weak

pub fn strong(&self) -> Option<&'shape Shape<'shape>>

Returns shape of the corresponding weak pointer, if this pointer is strong
