Struct SubmessageHeader 

pub struct SubmessageHeader {
    pub submessage_id: SubmessageId,
    pub flags: u8,
    pub octets_to_next_header: u16,
}

Submessage-Header.

Fields

submessage_id: SubmessageId

ID der Submessage-Klasse.

flags: u8

Flag-Byte (Bit 0 = E = Little-Endian-Body; weitere Bits submessage-spezifisch).

octets_to_next_header: u16

Body-Laenge in Bytes. 0 hat Spezial-Bedeutung (siehe Spec §8.3.4.2): Reader liest “bis Ende des Datagrams”.

Implementations

impl SubmessageHeader

pub const WIRE_SIZE: usize = 4

Wire-Size: 4 Bytes.

pub fn is_little_endian(self) -> bool

true, wenn das E-Flag gesetzt ist (LE-Body).

pub fn to_bytes(self) -> [u8; 4]

LE-Encoder. octets_to_next_header wird mit der durch is_little_endian() gegebenen Endianness geschrieben — der Sub-Header selbst nutzt dieselbe Endianness wie sein Body (Spec §8.3.4.1).

pub fn from_bytes(bytes: &[u8]) -> Result<Self, WireError>

Decoded einen 4-Byte-Slice.

Errors

UnexpectedEof, UnknownSubmessageId.

Trait Implementations

impl Clone for SubmessageHeader

fn clone(&self) -> SubmessageHeader

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SubmessageHeader

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for SubmessageHeader

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for SubmessageHeader

fn eq(&self, other: &SubmessageHeader) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
