§Codec
This crate provides a trait Codec and two (initial) implementations, Cbor and CborEncrypted.
A Codec value is a convenient abstraction over the lower level serialisation and crypto functions
in streambed.
A Codec is also closely associated with a CommitLog and a Topic since values stored on the commit
log under a given topic will all be encoded the same way.
The type LogAdapter is provided to wrap a Codec, CommitLog and Topic. A LogAdapter carries
a type parameter for the decoded log values. It can be viewed as a typed counterpart to CommitLog
The produce method on LogAdapter accepts a typed value, encodes it and appends it to the log.
The history method returns a Stream of typed values from the commit log.
Structs§
- Cbor
- A
Codecfor CBOR - Cbor
Encrypted - A
Codecfor encripted CBOR - LogAdapter
- Wraps a
CommitLogand specializes it for a specific payload type. This adds the type, topic and the encoding and encryption scheme.

Traits§
- Codec
- A trait for codecs for a specic type
A, usually an event type stored on a CommitLog. - Commit
Log - A commit log holds topics and can be appended to and tailed. Connections are managed and retried if they cannot be established.
- Commit
LogExt - Provides a method on
CommitLogto specialize it for a payload type.
