Ref

move keyword was not specified.

Trait Implementations

impl Clone for CaptureBy

fn clone(&self) -> CaptureBy

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for CaptureBy

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

Formats the value using the given formatter.

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

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

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

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

impl<__CTX> HashStable<__CTX> for CaptureBywhere
    __CTX: HashStableContext,

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

impl PartialEq<CaptureBy> for CaptureBy

fn eq(&self, other: &CaptureBy) -> 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 CaptureBy

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.
