Trait Implementations

Returns the “default value” for a type. Read more

Determines a trie root given its ordered contents, closed form.

Determines a trie root node’s data given its ordered contents, closed form.

Encoding of index as a key (when reusing general trie for indexed trie). Read more

Operation to build a trie db from its ordered iterator over its key/values.

A trie root formed from the items, with keys attached according to their compact-encoded index (using parity-codec crate). Read more

If true, the trie will use extension nodes and no partial in branch, if false the trie will only use branch and node with partials in both. Read more

If true, the trie will allow empty values into TrieDBMut

Hasher to use for this trie.

Codec to use (needs to match hasher and nibble ops).

Gets the TypeId of self. Read more

Immutably borrows from an owned value. Read more

Mutably borrows from an owned value. Read more

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

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

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

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

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

Performs the conversion.

Instruments this type with the provided Span, returning an Instrumented wrapper. Read more

Instruments this type with the current Span, returning an Instrumented wrapper. Read more

Performs the conversion.

Get a reference to the inner from the outer.

Get a mutable reference to the inner from the outer.

Should always be Self

The type returned in the event of a conversion error.

Performs the conversion.

The type returned in the event of a conversion error.

Performs the conversion.

The counterpart to unchecked_from.

Attaches the provided Subscriber to this type, returning a WithDispatch wrapper. Read more
