Trait Implementations

impl Clone for Constness

fn clone(&self) -> Constness

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Constness

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

Formats the value using the given formatter.

impl<__D> Decodable<__D> for Constness

where __D: SpanDecoder,

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

impl Display for Constness

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

Formats the value using the given formatter.

impl<__E> Encodable<__E> for Constness

where __E: SpanEncoder,

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

impl EraseType for Constness

type Result = [u8; 1]

impl<__CTX> HashStable<__CTX> for Constness

where __CTX: HashStableContext,

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

impl ParameterizedOverTcx for Constness

type Value<'tcx> = Constness

impl PartialEq for Constness

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