ASTERIX for golang

Documentation ¶

Overview ¶

Package gasterix provides a unified API for encoding and decoding ASTERIX data. It coordinates the block-level parsing with category-specific decoders.

Index ¶

type Block
- func Decode(data []byte) (*Block, int, error)
- func DecodeAll(data []byte) ([]*Block, error)
- func (b *Block) Cat62Tracks() []*cat62.Track
type Decoder
- func NewDecoder(r io.Reader) *Decoder
- func (d *Decoder) Decode() (*Block, error)
type Encoder
- func NewEncoder(w io.Writer) *Encoder
- func (e *Encoder) Encode(blk *Block) error

Functions ¶

func Encode ¶

func Encode(blk *Block) ([]byte, error)

Encode encodes a Block into raw bytes.

Types ¶

type Block ¶

type Block struct {
	Category uint8
	Records  []any // Category-specific record types (e.g., *cat62.Track)
}

Block represents a decoded ASTERIX data block with typed records.

func Decode ¶

func Decode(data []byte) (*Block, int, error)

Decode decodes a single ASTERIX block from raw bytes. Returns the decoded block and the number of bytes consumed.

func DecodeAll ¶

func DecodeAll(data []byte) ([]*Block, error)

DecodeAll decodes all ASTERIX blocks from raw bytes.

func (*Block) Cat62Tracks ¶

func (b *Block) Cat62Tracks() []*cat62.Track

Cat62Tracks is a helper to extract *cat62.Track records from a Block. Returns nil if the block is not category 62.

type Decoder ¶

type Decoder struct {
	// contains filtered or unexported fields
}

Decoder reads ASTERIX blocks from an input stream.

func NewDecoder ¶

func NewDecoder(r io.Reader) *Decoder

NewDecoder returns a new decoder that reads from r.

func (*Decoder) Decode ¶

func (d *Decoder) Decode() (*Block, error)

Decode reads and returns the next ASTERIX block from the stream. Returns io.EOF when there are no more blocks.

type Encoder ¶

type Encoder struct {
	// contains filtered or unexported fields
}

Encoder writes ASTERIX blocks to an output stream.

func NewEncoder ¶

func NewEncoder(w io.Writer) *Encoder

NewEncoder returns a new encoder that writes to w.

func (*Encoder) Encode ¶

func (e *Encoder) Encode(blk *Block) error

Encode writes an ASTERIX block to the stream.
