Enum sp_state_machine::BackendTrustLevel

source ·

pub enum BackendTrustLevel {
    Trusted,
    Untrusted,
}

Expand description

Storage backend trust level.

Variants§

§

Trusted

Panics from trusted backends are considered justified, and never caught.

§

Untrusted

Panics from untrusted backend are caught and interpreted as runtime error. Untrusted backend may be missing some parts of the trie, so panics are not considered fatal.

Gets the TypeId of self. Read more

source §

impl<T> Borrow<T> for Twhere T: ?Sized,

fn borrow(&self) -> &T

Immutably 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.

§

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.

§

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.

§

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.

§

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

§

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

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