DDlog v0.34.0

on GitHub

[0.34.0] - Jan 11, 2021

Bug fixes

• A change in serde caused DDlog-generated Rust code to stop compiling,
  affecting all recent DDlog releases.

API changes

• Removed callback argument from HDDlog::run, ddlog_run, and Go/Java language
  bindings based on ddlog_run. This optional callback, invoked by DD workers on
  each update to an output collection complicated the API and was tricky to use
  correctly. Most importantly, it is superseded by the commit_dump_changes API.

Added

• Added the ddlog_derive crate that provides derive macros for the FromRecord,
  IntoRecord and Mutator traits
• Added the Record::positional_struct_fields() method to allow fetching positional
  fields from records
• Added the Record::get_struct_field() method to allow getting a struct record's
  field by name
