Trait Implementations

impl Clone for Defaultness

fn clone(&self) -> Defaultness

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Defaultness

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

Formats the value using the given formatter.

impl<__D: Decoder> Decodable<__D> for Defaultness

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

impl<__E: Encoder> Encodable<__E> for Defaultness

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

impl<__CTX> HashStable<__CTX> for Defaultness

where __CTX: HashStableContext,

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

impl PartialEq for Defaultness

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl StructuralPartialEq for Defaultness

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.
