Struct Repr 

#[repr(C)]
pub struct Repr {
    pub base: BaseRepr,
    pub packed: bool,
}

Describes base representation of the type

Is the structure packed, is it laid out like a C struct, is it a transparent wrapper?

Fields

base: BaseRepr

Describes base layout representation of the type

packed: bool

Are the values tightly packed?

Note, that if struct is packed, the underlying values may not be aligned, and it is undefined behavior to interact with unaligned values - first copy the value to aligned buffer, before interacting with it (but first, make sure it is Copy!)

Implementations

impl Repr

pub const RUST: Self

Default Rust representation (unpacked)

pub const C: Self

C representation (unpacked)

pub const TRANSPARENT: Self

Transparent representation

pub const fn default() -> Self

Create default representation for a user type

This will be Rust representation with no packing

pub const fn c() -> Self

Build unpacked C representation

pub const fn transparent() -> Self

Builds transparent representation

Trait Implementations

impl Clone for Repr

fn clone(&self) -> Repr

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Repr

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

Formats the value using the given formatter.

impl Default for Repr

fn default() -> Repr

Returns the “default value” for a type.

impl Facet<'_> for Repr

const SHAPE: &'static Shape

The shape of this type, including: whether it’s a Struct, an Enum, something else?

impl Hash for Repr

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 Repr

fn eq(&self, other: &Repr) -> 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.

impl Copy for Repr

impl Eq for Repr

impl StructuralPartialEq for Repr
