This is a crate for Interprocess Communication via TCP.
It allows for easy, asynchronous sending and receiving messages/commands.
A flexible protocol is used, consisting of a command, a length and a payload.
In detail, it is expected that the used TCP protocol works via exchange of byte collections. A fixed header length is assumed, so - for example - the first 5 bytes of each message encode the message header. The header in turn consists of a command (like Stop, Start, Pause, Load, ...) and a length part. Command & length can be in arbitrary order (but have to be fixed for the protocol). Then the next length-many bytes which are received are the payload of the message. Further received bytes form the next message.
An example is given in the Examples.
The error type for a shutdown attemp.
This is the main type of the library. Here all the logic is bundle. It can be used to easily send and receive messages via TCP, allowing for many different protcols to be used.
This bundles the time-settings for the protocol A 'None' value means that there will no time spend waiting.
The error type for a BusyState query
The error type for a BusyState update
The error type for the connect-function.
The error type for parsing a header which was transferred via TCP.
The error type for operations in the asynchronous read thread
The error type for a message writing
This trait represents the TCP-Protocol to be used.
