View Source Estructura.LazyMap (estructura v1.4.1)
The implementation of lazy map implementing lazy Access for its keys.
Estructura.LazyMap is backed by the “raw” object and a key-value pairs
where values might be instances of Estructura.Lazy. If this is a case,
they will be accessed through Lazy implementation.
Values might be also raw values, which makes LazyMap a drop-in replacement
of standard Elixir maps, assuming they are accessed through Access
only (e. g. map[:key] and not map.key.)
Summary
Functions
Eagerly instantiates the data
Returns all the keys of the underlying map
Creates new instance of LazyMap with a second parameter being a backed up object,
which would be used for lazy retrieving data for values, when value is an instance
of Estructura.Lazy.
