Expand description

Information related to a child state.

Variants

ParentKeyId(ChildTrieParentKeyId)

This is the one used by default.

Implementations

Instantiates child information for a default child trie of kind ChildType::ParentKeyId, using an unprefixed parent storage key.

Same as new_default but with Vec<u8> as input.

Try to update with another instance, return false if both instance are not compatible.

Returns byte sequence (keyspace) that can be use by underlying db to isolate keys. This is a unique id of the child trie. The collision resistance of this value depends on the type of child info use. For ChildInfo::Default it is and need to be.

Returns a reference to the location in the direct parent of this trie but without the common prefix for this kind of child trie.

Return a the full location in the direct parent of this trie.

Returns a the full location in the direct parent of this trie.

Returns the type for this child info.
