[v0.3.0] - 2020-02-10

Refactored Errors:

  • Removed the error-chain dependency.
  • Errors are now implemented "manually" with ErrorKind and IoctlKind enums.
  • The encompassing Error type implements the std::error::Error trait.

v0.2.0 - 2018-12-12

Adds the ability to create a collection of lines from a single chip and read or write those lines simultaneously with a single stystem call.

  • A new Lines object (plural) was added. It is a collection of individual Line objects on a single Chip which can be read or written simultaneously with a single system call.
  • A Line now just contains the reference to the Chip and the offset number. No system call is incurred when one is created.
  • Information about an individual line is now represented by a separate LineInfo struct which can be obtained from the function Line::info(). This incurs a system call to retrieve the information.
  • Creating a Line can't fail unless the caller specifies an offset that is out of range of the chip.
  • The LineIterator can not fail since it checks the offset range. So now its item is just a Line, and not Result<Line>.
  • There was no longer a need for Line::refresh() so it was removed.
  • Since a Line object is trivial to create, it is now OK to have Lines be a simple collection of Line structs.

v0.1.0 - 2018-09-28

  • Initial release of the library with basic operations centered around operating on a single line at a time.
