Trait Implementations

impl Clone for ImplPolarity

fn clone(&self) -> ImplPolarity

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ImplPolarity

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

Formats the value using the given formatter.

impl<__D> Decodable<__D> for ImplPolarity

where __D: SpanDecoder,

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

impl<__E> Encodable<__E> for ImplPolarity

where __E: SpanEncoder,

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

impl<__CTX> HashStable<__CTX> for ImplPolarity

where __CTX: HashStableContext,

fn hash_stable( &self, __hcx: &mut __CTX, __hasher: &mut StableHasher<SipHasher128>, )

impl PartialEq for ImplPolarity

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

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.
