1. <start_uuid>.limlog and <start_uuid>.idx are used to store sequential messages.
2. TODO

Structs

• Reader
  A reader to read logs from a topic with [Stream] interface.
• Topic
  The topic which is used to read and write logs. Background task will keep running even if this struct is dropped. To stop the task, call stop or abort.
• TopicBuilder
  Builds Topic with custom configuration values.
• Writer
  A writer to write logs to a topic.

Enums

• ErrorType
  The Limlog error type.

Functions

• bincode_option
• try_decode
  Try to decode from stream of bytes with bincode. Notice that this takes &[u8] instead of &mut &[u8], so cursor won’t be updated. Instead, bytes read will be returned along with the deserialized value.

Type Definitions

• BincodeOptions
• Result
  A specialized Result type for Limlog.
