Implementations

impl UpdateVolatilityRing

Trait Implementations

impl Archive for UpdateVolatilityRing

where MessageId: Archive, CorrelationId: Archive, u64: Archive, i64: Archive,

type Archived = ArchivedUpdateVolatilityRing

The archived representation of this type.

type Resolver = UpdateVolatilityRingResolver

unsafe fn resolve( &self, pos: usize, resolver: Self::Resolver, out: *mut Self::Archived, )

Creates the archived version of this value at the given position and writes it to the given output.

impl Clone for UpdateVolatilityRing

fn clone(&self) -> UpdateVolatilityRing

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for UpdateVolatilityRing

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

Formats the value using the given formatter.

impl<__D: Fallible + ?Sized> Deserialize<UpdateVolatilityRing, __D> for Archived<UpdateVolatilityRing>
