Module map_view

The MapView implements a map with ordered keys. The MapView implements a map that can be modified.

This reproduces more or less the functionalities of the BTreeMap. There are 3 different variants:

• The ByteMapView whose keys are the Vec<u8> and the values are a serializable type V. The ordering of the entries is via the lexicographic order of the keys.
• The MapView whose keys are a serializable type K and the value a serializable type V. The ordering is via the order of the BCS serialized keys.
• The CustomMapView whose keys are a serializable type K and the value a serializable type V. The ordering is via the order of the custom serialized keys.

Structs

• ByteMapView
  A view that supports inserting and removing values indexed by Vec<u8>.
• CustomMapView
  A map view that uses custom serialization
• MapView
  A View that has a type for keys. The ordering of the entries is determined by the serialization of the context.

Type Aliases

• HashedByteMapView
  Type wrapping ByteMapView while memoizing the hash.
• HashedCustomMapView
  Type wrapping CustomMapView while memoizing the hash.
• HashedMapView
  Type wrapping MapView while memoizing the hash.
