[−][src]Struct sp_storage::ChildStorageKey

pub struct ChildStorageKey<'a> { /* fields omitted */ }

A wrapper around a child storage key.

This wrapper ensures that the child storage key is correct and properly used. It is impossible to create an instance of this struct without providing a correct storage_key.

Methods

impl<'a> ChildStorageKey<'a>[src]

pub fn from_vec(key: Vec<u8>) -> Option<Self>[src]

Create a new ChildStorageKey from a vector.

storage_key need to start with :child_storage:default: See is_child_trie_key_valid for more details.

pub fn from_slice(key: &'a [u8]) -> Option<Self>[src]

Create a new ChildStorageKey from a slice.

storage_key need to start with :child_storage:default: See is_child_trie_key_valid for more details.

pub fn as_ref(&self) -> &[u8][src]

Get access to the byte representation of the storage key.

This key is guaranteed to be correct.

pub fn into_owned(self) -> Vec<u8>[src]

Destruct this instance into an owned vector that represents the storage key.

This key is guaranteed to be correct.
