File_replaced occurs if the inode of the file changed and the file tail was configured with ignore_inode_change = false.

create file opens file, creating it if it doesn't exist.

create ?message path tries to create a file at path containing the text message, pid if none provided.

create f returns a t, given a function that actually performs the final output work.

Implements a value that is either in a file, or in memory, but not both.

A library for building asynchronous RPC-style protocols.

Initiate an Rpc connection on the given reader/writer pair.

with_connection ~host ~port f looks up host from a string (using DNS as needed), connects, then calls f passing in a reader and a writer for the connected socket.

serve ~port () must be called before clients will be able to connect.

Unpack_sequence implements a way to take an unpack_one function that can unpack a value from a character buffer, and use it to unpack a sequence of packed values coming via a string pipe into a pipe of upacked values.

Infrastructure code for managing RPCs which evolve over time to use different types at different versions

This module describes the type of a given direction of message flow.
