# cbor-core
A deterministic CBOR::Core encoder and decoder for Rust, tracking
`draft-rundgren-cbor-core-25`.
## 0.7.0
- CBOR sequences are now supported on both sides, with
iterator-style decoding from byte slices or readers and a
streaming writer for byte, hex, and diagnostic output.
- Decoder configuration moved into a dedicated options type that
bundles the input format, recursion limit, collection length
limit, and OOM-mitigation budget.
- Diagnostic notation joined the binary and hex formats as a
first-class decoder input, with the same hardening limits and
proper error variants for nesting and trailing data.
- The constructor surface grew a full set of explicit and `const`
builders for scalar values.
- Non-finite floats can now be constructed from and inspected as a
53-bit payload, so signaling NaNs and other non-finite bit
patterns are addressable directly and round-trip unchanged.
- Composite map keys (arrays and maps used as keys) now look up
without a preparatory allocation.
- An optional `jiff` feature joins the existing `chrono` and `time`
integrations.
- A small number of signature cleanups on the write and decode
entry points; see the changelog for the exact breaking items.
- First set of runnable examples ships with the crate, covering
encoding and decoding of values and sequences, a pair of
`cbor2diag` / `diag2cbor` conversion utilities, and short
walkthroughs of the macros and `const` constructors.
