comtrade - Pure Rust library for parsing COMTRADE files.

Warning: this library is a WIP and not yet ready for production usage.

This library provides a native Rust library for parsing COMTRADE (Common format for Transient Data Exchange for power systems) files, containing oscillography and status data for power system disturbances.

Implementation status

Task	Status
Implement parsing .cfg files (encoded in ASCII)	Done (1991, 1999, 2013)
Implement parsing .cfg files (encoded in UTF-8)	Done
Implement parsing .cfg files (encoded in other encodings such as latin1)	Not tested
Implement parsing ASCII data files	Done
Implement parsing binary16 data files	Done
Implement parsing binary32 data files	Done (not tested)
Implement parsing float32 data files	Done (not tested)
Implement loading separate files from combined 2013 .cff format.	Done
Implement retrieval of actual analog data values using primary vs. secondary factors, offsets, etc.	Adders & multipliers done; primary vs. secondary todo
Implement calculation of real time based on time multipliers, etc. (critical & non-critical timestamps)	Done
Support for channel-specific timestamp skews	Todo

Getting started

Todo: once ready, deploy to crates.io.

Usage

Todo: document usage.

Todo

• Clean up error messages - maybe have consistent format including filename and line number?
• Add warnings for non-critical data missing and errors for critical data missing.
• Add warnings for unexpected values (but not errors) for things like channel numbers not adding up, etc.
• Test files:
  • Binary32 and float32 data files.
  • Missing non-critical data.
  • Continuously variable sample rate (i.e. crticial timestamp).
  • Multiple sample rates.
