Struct Shape

pub struct Shape {
    pub name: &'static str,
    pub typeid: TypeId,
    pub layout: Layout,
    pub innards: Innards,
    pub set_to_default: Option<fn(*mut u8)>,
    pub drop_in_place: Option<DropFunction>,
}

Schema for reflection of a type

Fields

name: &'static str

A descriptive name for the type, e.g. u64, or Person

typeid: TypeId

The typeid of the underlying type

layout: Layout

Size & alignment

innards: Innards

Details/contents of the value

set_to_default: Option<fn(*mut u8)>

Set the value at a given address to the default value for this type

drop_in_place: Option<DropFunction>

Drop the value at a given address

Safety

This function should be called only for initialized values. It’s the caller’s responsibility to ensure the address points to a valid value.

Implementations

impl Shape

pub fn pretty_print_recursive(&self, f: &mut Formatter<'_>) -> Result

Pretty-print this shape, recursively.

Trait Implementations

impl Clone for Shape

fn clone(&self) -> Shape

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Shape

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for Shape

fn hash<H: Hasher>(&self, state: &mut H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Shape

fn eq(&self, other: &Self) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
