Enum TraitObjectSyntax

#[repr(u8)]
pub enum TraitObjectSyntax {
    Dyn = 0,
    DynStar = 1,

Syntax used to declare a trait object.

Variants

Dyn = 0

DynStar = 1

None = 2

Trait Implementations

impl Clone for TraitObjectSyntax

fn clone(&self) -> TraitObjectSyntax

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TraitObjectSyntax

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

Formats the value using the given formatter.

impl<__D: SpanDecoder> Decodable<__D> for TraitObjectSyntax

fn decode(__decoder: &mut __D) -> Self

impl<__E: SpanEncoder> Encodable<__E> for TraitObjectSyntax

fn encode(&self, __encoder: &mut __E)

impl<__CTX> HashStable<__CTX> for TraitObjectSyntax

where __CTX: HashStableContext,

fn hash_stable(&self, __hcx: &mut __CTX, __hasher: &mut StableHasher)

impl PartialEq for TraitObjectSyntax

fn eq(&self, other: &TraitObjectSyntax) -> 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 Tag for TraitObjectSyntax

SAFETY: TraitObjectSyntax only has 3 data-less variants which means it can be represented with a u2. We use repr(u8) to guarantee the discriminants of the variants are no greater than 3.

const BITS: u32 = 2u32

Number of least-significant bits in the return value of into_usize which may be non-zero. In other words this is the bit width of the value.

fn into_usize(self) -> usize

Turns this tag into an integer.

unsafe fn from_usize(tag: usize) -> Self

Re-creates the tag from the integer returned by into_usize.

impl StructuralPartialEq for TraitObjectSyntax

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
