Crate cbor_nan_bstr 

A CBOR Tag for Lossless Transport of IEEE‑754 NaN Bit Patterns Implements draft‑mcnally‑cbor‑nan‑bstr semantics for dCBOR.

This module defines a NanBstr tagged value that carries the exact bit pattern of an IEEE‑754 NaN in a CBOR byte string, tagged with 102.

The enclosed byte string MUST be exactly 2, 4, 8, or 16 bytes long and is interpreted in network byte order (big‑endian). Its bits MUST encode a NaN for the corresponding interchange width; no canonicalization of sign, quiet/signaling, payload, or width is performed here.

NOTE: This includes binary128 (f128) support without using any native f128 type: APIs accept/return raw bit patterns as u128 or [u8; 16].

Structs

NanBstr

A CBOR-friendly wrapper for an IEEE‑754 NaN bit pattern transported as a byte string and tagged with CBOR tag 102 (“nan-bstr”).

Enums

Error

Error types for cbor-nan-bstr

NanWidth

Width of the underlying IEEE‑754 representation carried in the byte string.

Type Aliases

Result

A specialized Result type for cbor-nan-bstr operations.
