Implementations

source

impl KeyValueStates

source

Trait Implementations

impl Clone for KeyValueStates

source

fn clone(&self) -> KeyValueStates

Returns a copy of the value. Read more

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

Performs copy-assignment from source. Read more

source

impl From for KeyValueStateswhere
I: IntoIterator<Item = (Vec<u8>, (Vec<(Vec<u8>, Vec<u8>)>, Vec<Vec<u8>>))>,

source

fn from(b: I) -> Self

Converts to this type from the input type.

source

impl PartialEq<KeyValueStates> for KeyValueStates

source

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

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

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. Read more

fn borrow(&self) -> &T

Immutably borrows from an owned value. Read more

Mutably borrows from an owned value. Read more

impl<T> Downcast for Twhere
T: Any,

fn into_any(self: Box<T, Global>) -> Box<dyn Any + 'static, Global>

Convert Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>. Box<dyn Any> can then be further downcast into Box<ConcreteType> where ConcreteType implements Trait. Read more

fn into_any_rc(self: Rc<T>) -> Rc<dyn Any + 'static>

Convert Rc<Trait> (where Trait: Downcast) to Rc<Any>. Rc<Any> can then be further downcast into Rc<ConcreteType> where ConcreteType implements Trait. Read more

fn as_any(&self) -> &(dyn Any + 'static)

Convert &Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &Any’s vtable from &Trait’s. Read more

fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)

Convert &mut Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &mut Any’s vtable from &mut Trait’s. Read more

impl<T> DowncastSync for Twhere
T: Any + Send + Sync,

fn into_any_arc(self: Arc<T>) -> Arc<dyn Any + Sync + Send + 'static>

Convert Arc<Trait> (where Trait: Downcast) to Arc<Any>. Arc<Any> can then be further downcast into Arc<ConcreteType> where ConcreteType implements Trait. Read more
