MSeed.NIF (wsdataselect v1.2.0)

This module calls external NIF in C in order to fetch mseed data efficiently

Summary

Fetch miniSeed records corresponding the the DataFile given in parameter. This will use a NIF to make efficient use of the libmseed.

on_load()

Function called on module load. It declares the shared library that contains the functions our NIF defines.

Fetch all miniseed records in parallel. Stream the output data to caller function The idea is to minimize latency when fetching data Look for https://hexdocs.pm/elixir/Stream.html Read https://medium.com/elemental-elixir/processing-very-large-text-files-in-elixir-b631792eed59
