Struct PointerDef 

#[repr(C)]
pub struct PointerDef {
    pub vtable: &'static PointerVTable,
    pub pointee: Option<fn() -> &'static Shape>,
    pub weak: Option<fn() -> &'static Shape>,
    pub strong: Option<fn() -> &'static 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: &'static PointerVTable

vtable for interacting with the pointer

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

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

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

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

strong: Option<fn() -> &'static 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 PointerDef

pub const fn builder() -> PointerDefBuilder

Creates a new PointerDefBuilder with all fields set to None.

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

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

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

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

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

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