Functions§

  • provided_to_erased
    This function takes ProvidedValue and coverts it to an erased Value by allocating it on an arena if the query has the arena_cache modifier. The value is then erased and returned. This will happen when computing the query using a provider or decoding a stored result.

Type Aliases§

  • Key
  • LocalKey
  • ProvidedValue
    This type alias specifies the type returned from query providers and the type used for decoding. For regular queries this is the declared returned type V, but arena_cache will use <V as Deref>::Target instead.
  • Storage
  • Value
