impl<T: Eq + Trait> Eq for Reaction<T>

impl<T: Trait> From<Reaction<T>> for FlatReaction<T::AccountId, T::BlockNumber>

fn from(from: Reaction<T>) -> Self

Performs the conversion.

impl<T: PartialEq + Trait> PartialEq<Reaction<T>> for Reaction<T>

fn eq(&self, other: &Reaction<T>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Reaction<T>) -> bool

This method tests for !=.

impl<T: Trait> StorageMap<u64, Reaction<T>> for ReactionById<T>

type Query = Option<Reaction<T>>

The type that get/take returns.

type Hasher = Twox64Concat

Hasher. Used for generating final key.

fn module_prefix() -> &'static [u8]

Module prefix. Used for generating final key.

fn storage_prefix() -> &'static [u8]

Storage prefix. Used for generating final key.

fn from_optional_value_to_query(v: Option<Reaction<T>>) -> Self::Query

Convert an optional value retrieved from storage to the type queried.

fn from_query_to_optional_value(v: Self::Query) -> Option<Reaction<T>>

Convert a query to an optional value into storage.

pub fn prefix_hash() -> Vec<u8, Global>

The full prefix; just the hash of module_prefix concatenated to the hash of storage_prefix.

pub fn storage_map_final_key<KeyArg>(key: KeyArg) -> Vec<u8, Global> where
    KeyArg: EncodeLike<K>, 

Generate the full key used in top storage.

impl<T: Trait> StoragePrefixedMap<Reaction<T>> for ReactionById<T>

fn module_prefix() -> &'static [u8]

Module prefix. Used for generating final key.

fn storage_prefix() -> &'static [u8]

Storage prefix. Used for generating final key.

pub fn final_prefix() -> [u8; 32]

Final full prefix that prefixes all keys.

pub fn remove_all()

Remove all value of the storage.

pub fn iter_values() -> PrefixIterator<Value>

pub fn translate_values<OldValue, F>(f: F) where
    F: Fn(OldValue) -> Option<Value>,
    OldValue: Decode, 

Translate the values of all elements by a function f, in the map in no particular order. By returning None from f for an element, you’ll remove it from the map.
