Hamilton::Context

Context is a storage for some state.

As it was developed primary for Hamilton::CmdHandler, Hamilton::Context maps a key of type Int64 | String | Symbol to a named tuple with two fields:

method : Symbol | Nil -- name of some method
data: Hamilton::Storage) -- storage for some specific data

Constructors

Initializer of the context storage.

Optional parameters: default_method : Symbol | Nil -- something that will be the default value for the method field inner : Hash(Int32 | String | Symbol, NamedTuple(method: Symbol | Nil, data: Hamilton::Storage)) -- storage itself

Reset the context for the key, i.e. the key will map to {method: default_method, data: nil} if present.

Source

clean_data(key : Int64 | String | Symbol)

Reset the data for the key.

Source

clean_method(key : Int64 | String | Symbol)
