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 (behind ais feature) and AIS application-layer sentences

Features

• nmea (default) — all 59 NMEA sentence types
• ais (default) — 16 AIS message types (read-only decode) + AIS application-layer sentences
• dbs, dbt, dpt, … — individual sentence types

Re-exports

pub use nmea::NmeaSentence;

pub use nmea::NmeaEncodable;

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

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.
