Module error 

BACnet error types.

Provides the top-level Error type used throughout the library, covering protocol errors, encoding/decoding failures, transport issues, and timeouts.

Without alloc it keeps only the variants that own nothing: a decoder’s DecodeError, an encoder’s EncodeError, a constructor’s RangeError and a segmenter’s SegmentationError carry static labels or numbers and build their text when displayed (#1646, #1802). The variants holding a String or a Box need alloc.

Structs

DecodeError

A decoder’s refusal, without an allocated message (#1646).

EncodeError

A value an encoder or validator refused to put on the wire, without an allocated message (#1802).

RangeError

A value a checked constructor refused for lying outside the range its type takes, such as an object instance past 4,194,303 (#1646).

Enums

DecodingKind

Which fault a decoder found in the data it refused, so a responder can name it (#1446). DecodingKind::reject_reason gives the Clause 18.9 Reject reason each kind draws when the data was a confirmed request.

Error

Top-level error type for the BACnet library.

ErrorDetail

The fields a Clause 21 error production adds to the error class and code, one variant per shape. The service the error answers names the production. Only with alloc.

ReadRangeViolation

A rule a ReadRange acknowledgement can break against the request it answers (Clause 15.8).

RemoteError

How a peer turned a confirmed request down: an Error PDU’s class and code, or a Reject or Abort PDU’s reason (Clauses 20.1.5 to 20.1.7).

SegmentationError

Why a payload could not be split into segments, or its segments put back together, or a segmented request sent (#1802).

Type Aliases

Result

Convenience alias for Result<T, Error>.
