Struct Partial

pub struct Partial<'s> { /* private fields */ }

A partially-initialized shape, useful when deserializing for example.

Implementations

impl Partial<'_>

pub fn alloc(shape_desc: ShapeDesc) -> Self

Allocates a partial on the heap for the given shape descriptor.

pub fn borrow<T: Shapely>(uninit: &mut MaybeUninit<T>) -> Self

Borrows a MaybeUninit<Self> and returns a Partial.

Before calling assume_init, make sure to call Partial.build_in_place().

pub fn scalar_slot(&mut self) -> Option<Slot<'_>>

Returns a slot for assigning this whole shape as a scalar

pub fn slot<'s>(&'s mut self, field: Field<'_>) -> Option<Slot<'s>>

Returns a slot for initializing a field in the shape.

pub fn build_in_place(self)

pub fn build<T: Shapely>(self) -> T

pub fn build_boxed<T: Shapely>(self) -> Box<T>

pub fn shape_desc(&self) -> ShapeDesc

pub fn addr_for_display(&self) -> *const u8

Returns the address of the underlying data — for debugging purposes only. Returns null if the data is zero-sized.

pub unsafe fn move_into(self, target: *mut u8)

Safety

The target pointer must be valid and properly aligned, and must be large enough to hold the value.

Trait Implementations

impl Drop for Partial<'_>

fn drop(&mut self)

Executes the destructor for this type.
