Module perlin::storage
[−]
[src]
This module contains the trait Storage
and implementations of it.
Storage
s are used by implementators of the Index
trait to store and
retrieve their sometimes complex and huge datastructures
For small collections, a RamStorage
will suffice. If the collections are
larger than the size of RAM though, a different solution is needed.
To enable flexibility and perhaps even use case specific user
implementations, this trait serves as an interface for Indices to be use.
Current implementations are RamStorage
for smaller collections that fit
completely in RAM and FsStorage
which writes and reads data from disk and
thus allows the handling of much larger collections.
Structs
FsStorage |
Writes datastructures to a filesystem. Compressed and retrievable. |
RamStorage |
Stores anything in a |
VByteDecoder |
Iterator that decodes a bytestream to unsigned integers |
Enums
StorageError |
Errors that can occur during retrieval or storage of a value |
Traits
ByteDecodable |
Defines a method that allows an object to be decoded from a variable number of bytes |
ByteEncodable |
Defines a method that allows an object to be encoded as a variable number of bytes |
Storage |
Defines a common interface between multiple storage types The index uses them to store data like the posting lists |
Functions
vbyte_encode |
Encode an usigned integer as a variable number of bytes |
