Release Notes

ron-rs/ron (ron)

v0.12.0

Compare Source

API Changes

• Breaking: Removed the ron::error::Error::Base64Error variant. (#​566)
• Added into_inner() method to ron::ser::Serializer to retrieve the inner writer. (#​588)
• Removed the base64 dependency. (#​566)

Format Changes

• Format-Breaking: Remote base64-encoded byte strings deserialisation, replaced by Rusty byte strings in v0.9.0 (#​566)

Bug Fixes

• Fixed untagged enum deserialisation for serde >= 1.0.220 with better serde content detection (#​582)

v0.11.0

Compare Source

API Changes

• Breaking: SpannedError now stores the full error span in span: Span { start: Position, end: Position }`, to facilitate, e.g., language server highlighting of syntax errors.
• Breaking: Added no_std support via a new std feature (enabled by default). With default features disabled, you must enable the std feature to access de::from_reader, and the std::io operations on Options, such as from_reader, from_reader_seed, to_io_writer, and to_io_writer_pretty (#​567)
• Breaking: Fixed (again) ron::value::Number to ensure it is non-exhaustive, to avoid breaking matches when feature unification enables more of its variants than expected (#​568)

Examples

• Add a new example file_read_write_vec.rs for reading and writing Vec<T> to/from files. (#​573)

v0.10.1

API Changes

• Add ron::Options::to_io_writer and ron::Options::to_io_writer_pretty to allow writing into an io::Writer (#​561)
• Breaking: ron::value::Number is now non-exhaustive, to avoid breaking matches when feature unification enables more of its variants than expected (#​564)

• Bump MSRV to 1.64.0 and bump dependency: indexmap to 2.0 (#​459)
