Struct LateFieldDescriptor 

pub struct LateFieldDescriptor<S: LateStruct> { /* private fields */ }

A typed descriptor for a LateField.

You can obtain a reference to this descriptor using LateField::descriptor.

Unlike LateFieldDescriptor, this descriptor encodes the type of the LateStruct to which the field belongs.

Implementations

impl<S: LateStruct> LateFieldDescriptor<S>

pub const fn raw(&self) -> &RawLateFieldDescriptor

Erases the type information from this descriptor, producing its equivalent RawLateFieldDescriptor.

impl<S: LateStruct> LateFieldDescriptor<S>

pub fn index(&self, token: LateLayoutInitToken) -> usize

Forwards to RawLateFieldDescriptor::index.

pub fn offset(&self, token: LateLayoutInitToken) -> usize

Forwards to RawLateFieldDescriptor::offset.

pub fn layout(&self) -> Layout

Forwards to RawLateFieldDescriptor::layout.

pub unsafe fn init(&self, value: *mut u8)

Forwards to RawLateFieldDescriptor::init.

Safety

See safety docs of RawLateFieldDescriptor::init.

pub unsafe fn drop(&self, value: *mut u8)

Forwards to RawLateFieldDescriptor::drop.

Safety

See safety docs of RawLateFieldDescriptor::drop.

pub fn erase_value(&self, value: *mut u8) -> *mut S::EraseTo

Forwards to RawLateFieldDescriptor::erase_value but uses type information to make the operation safe.

pub fn key_type_name(&self) -> &'static str

Forwards to RawLateFieldDescriptor::key_type_name.

pub fn key_type_id(&self) -> TypeId

Forwards to RawLateFieldDescriptor::key_type_id.

pub fn parent_struct(&self) -> &'static LateStructDescriptor<S>

Forwards to RawLateFieldDescriptor::parent_struct but preserves the type annotation.
