Mnemonix v0.6.2 Mnemonix.Stores.Map
A Mnemonix.Store
that uses a map to store state.
Intended to be an example for implementing the Mnemonix.Store.Behaviour
and
experimenting with the Mnemonix
API rather than production usage.
It intentionally doesn’t override any optional callback with native versions so that the default implementations can be easily tested.
iex> {:ok, store} = Mnemonix.Stores.Map.start_link
iex> Mnemonix.put(store, "foo", "bar")
iex> Mnemonix.get(store, "foo")
"bar"
iex> Mnemonix.delete(store, "foo")
iex> Mnemonix.get(store, "foo")
nil

Callback implementation for c:Mnemonix.Store.Behaviours.Map.delete/2
.
fetch(Mnemonix.Store.t, Mnemonix.key) :: {:ok, Mnemonix.Store.t, {:ok, Mnemonix.value} | :error} | Mnemonix.Store.Behaviour.exception
Callback implementation for c:Mnemonix.Store.Behaviours.Map.fetch/2
.
put(Mnemonix.Store.t, Mnemonix.key, Mnemonix.Store.value) :: {:ok, Mnemonix.Store.t} | Mnemonix.Store.Behaviour.exception
Callback implementation for c:Mnemonix.Store.Behaviours.Map.put/3
.
Constructs a map to store data.
Options
initial:
An existing map to start the store with.Default:
%{}
Starts a new Mnemonix.Store.Server
using the Mnemonix.Stores.Map
module with options
.
The options
are the same as described in Mnemonix.Store.Server.start_link/2
.
The returned GenServer.server/0
reference can be used as the primary
argument to the Mnemonix
API.
Examples
iex> {:ok, store} = Mnemonix.Stores.Map.start_link
iex> Mnemonix.put(store, "foo", "bar")
iex> Mnemonix.get(store, "foo")
"bar"
iex> {:ok, _store} = Mnemonix.Stores.Map.start_link([], [name: My.Mnemonix.Stores.Map])
iex> Mnemonix.put(My.Mnemonix.Stores.Map, "foo", "bar")
iex> Mnemonix.get(My.Mnemonix.Stores.Map, "foo")
"bar"
start_link(Mnemonix.Store.Server.options, GenServer.options) :: GenServer.on_start
Starts a new Mnemonix.Store.Server
using the Mnemonix.Stores.Map
with store
and server
options.
The options are the same as described in Mnemonix.Store.Server.start_link/3
.
The returned GenServer.server/0
reference can be used as the primary
argument to the Mnemonix
API.
Examples
iex> {:ok, store} = Mnemonix.Stores.Map.start_link([], [])
iex> Mnemonix.put(store, "foo", "bar")
iex> Mnemonix.get(store, "foo")
"bar"
iex> {:ok, _store} = Mnemonix.Stores.Map.start_link([], [name: My.Mnemonix.Stores.Map])
iex> Mnemonix.put(My.Mnemonix.Stores.Map, "foo", "bar")
iex> Mnemonix.get(My.Mnemonix.Stores.Map, "foo")
"bar"
