Trait StorageTrieEntryLike 

pub trait StorageTrieEntryLike: Sized {
    type SubKey: Clone;

    // Required methods
    fn nibbles(&self) -> &Self::SubKey;
    fn node(&self) -> &BranchNodeCompact;
    fn into_parts(self) -> (Self::SubKey, BranchNodeCompact);
    fn new(nibbles: Self::SubKey, node: BranchNodeCompact) -> Self;
}

Trait for storage trie entry types that carry a subkey and node.

Needed because [StorageTrieEntry] and [PackedStorageTrieEntry] are separate structs with different field types, but DatabaseStorageTrieCursor must access .nibbles() and .node() generically through A::StorageValue.

Required Associated Types

type SubKey: Clone

The subkey type.

Required Methods

fn nibbles(&self) -> &Self::SubKey

Returns a reference to the nibbles subkey.

fn node(&self) -> &BranchNodeCompact

Returns a reference to the branch node.

fn into_parts(self) -> (Self::SubKey, BranchNodeCompact)

Decompose this value into owned parts.

fn new(nibbles: Self::SubKey, node: BranchNodeCompact) -> Self

Construct a new entry from a subkey and node.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
