Crate dvb_ule 

👎Deprecated since 0.1.1:

renamed to ule; update your Cargo.toml

Deprecated — this crate has been renamed to ule.

Add ule to your Cargo.toml instead of dvb-ule. This shim re-exports everything from ule and will be removed in a future release.

Structs

PayloadChain

The decoded payload area of an SNDU (RFC 4326 §5): a chain of extension headers terminated by a final TypeField (an EtherType, or the introducing Type of a trailing Mandatory header) and the opaque PDU bytes.

Sndu

A parsed/owned SubNetwork Data Unit (RFC 4326 §4).

UleReceiver

A de-fragmenting ULE receiver (RFC 4326 §7).

Enums

Error

A ULE parse / serialize error.

ExtensionHeader

A single ULE extension header in a chain (RFC 4326 §5).

MandatoryHType

Typed H-Type for a Mandatory extension header (H-LEN = 0, RFC 4326 §5).

OptionalHType

Typed H-Type for an Optional extension header (H-LEN = 1..=5, RFC 4326 §5).

TypeField

A decoded ULE Type field (RFC 4326 §4.4).

Constants

BASE_HEADER_LEN

Size in bytes of the SNDU base header (D + Length + Type).

CRC_LEN

Size in bytes of the CRC-32 trailer.

END_INDICATOR

The two-byte value (D = 1, Length = 0x7FFF) that marks an End Indicator.

END_INDICATOR_LENGTH

The 15-bit Length value of an End Indicator — all length bits set.

ETHERTYPE_BOUNDARY

The boundary between Next-Header codes and EtherTypes (RFC 4326 §4.4): decimal 1536. Values below are Next-Headers; values at or above are EtherTypes.

ETHERTYPE_IPV4

IPv4 EtherType (RFC 4326 §4.7.2).

ETHERTYPE_IPV6

IPv6 EtherType (RFC 4326 §4.7.3).

H_TYPE_BRIDGED_FRAME

H-Type of the Bridged-Frame mandatory extension header (RFC 4326 §5.2).

H_TYPE_EXT_PADDING

H-Type of the Extension-Padding optional extension header (RFC 4326 §5.3), IANA value 0x100 → H-Type byte 0x00, H-LEN 1..=5.

H_TYPE_PDU_CONCAT

H-Type of the PDU-Concat mandatory extension header (RFC 5163 §3.2).

H_TYPE_TEST_SNDU

H-Type of the Test-SNDU mandatory extension header (RFC 4326 §5.1).

H_TYPE_TIMESTAMP

H-Type of the TimeStamp optional extension header (RFC 5163 §3.3), decimal 257 → H-Type byte 0x01 with H-LEN = 3.

H_TYPE_TS_CONCAT

H-Type of the MPEG-2 TS-Concat mandatory extension header (RFC 5163 §3.1).

NPA_LEN

Size in bytes of the Destination NPA address (present when D = 0).

PADDING_BYTE

The 0xFF byte used for TS-payload padding / stuffing (§4.3, §6).

TS_PAYLOAD_LEN

The number of TS-packet payload bytes when AFC = 01 (payload only): the 188-byte packet minus its 4-byte header (RFC 4326 §3).

Functions

is_end_indicator

true if the two bytes at the start of data are a ULE End Indicator (0xFFFF: D = 1, Length = 0x7FFF) — no further SNDUs in this TS packet (RFC 4326 §4.3).

Type Aliases

Result

Result alias for ULE parsing.
