Public API

• parse_frame / encode_frame — frame layer (always available)
• NmeaSentence — dispatch enum for all typed NMEA sentences
• NmeaEncodable — trait for encoding NMEA sentences to wire format
• ais — AIS decoder, transponder-message encoder, and !-prefixed AIS application sentences

Features

• nmea (default) — all 80 NMEA sentence types
• ais (default) — decoding for all numeric AIS Types 1-27, encoder support for Types 1/2/3, 4, 5, 9, 11, 12, 14, 18, 19, 21, 24 and 27, plus ABM/BBM application sentences
• dbs, dbt, dpt, … — individual sentence types

Re-exports

Modules

ais

AIS (Automatic Identification System) message decoding and application-layer sentences.

nmea

NMEA 0183 sentence parsing and encoding.

Structs

NmeaFrame

A parsed NMEA 0183 frame with references into the original input.

Enums

EncodeError

Errors from encoding (invalid frame parts or field values).

FrameError

Errors from frame-level parsing (checksum, delimiters, tag blocks).

Functions

encode_frame

Encode fields into a valid NMEA 0183 sentence string.

parse_frame

Parse a raw NMEA 0183 line into a validated frame.
