Module frame_support::storage::unhashed

Operation on unhashed runtime storage.

Functions

• clear_prefix
  Partially clear the storage of all keys under a common prefix.
• contains_prefixed_key
  Returns true if the storage contains any key, which starts with a certain prefix, and is longer than said prefix. This means that a key which equals the prefix will not be counted.
• exists
  Check to see if key has an explicit entry in storage.
• get
  Return the value of the item in storage under key, or None if there is no explicit entry.
• get_or
  Return the value of the item in storage under key, or default_value if there is no explicit entry.
• get_or_default
  Return the value of the item in storage under key, or the type’s default if there is no explicit entry.
• get_or_else
  Return the value of the item in storage under key, or default_value() if there is no explicit entry.
• get_raw
  Get a Vec of bytes from storage.
• kill
  Ensure key has no explicit entry in storage.
• kill_prefixDeprecated
  Ensure keys with the given prefix have no entries in storage.
• put
  Put value in storage under key.
• put_raw
  Put a raw byte slice into storage.
• take
  Remove key from storage, returning its value if it had an explicit entry or None otherwise.
• take_or
  Return the value of the item in storage under key, or default_value if there is no explicit entry. Ensure there is no explicit entry on return.
• take_or_default
  Remove key from storage, returning its value, or, if there was no explicit entry in storage, the default for its type.
• take_or_else
  Return the value of the item in storage under key, or default_value() if there is no explicit entry. Ensure there is no explicit entry on return.
