Struct Packet 

pub struct Packet<T: AsRef<[u8]>> { /* private fields */ }

A read/write wrapper around a SOME/IP-SD packet buffer.

SOME/IP-SD message format:

• Flags (1 byte)
• Reserved (3 bytes)
• Length of Entries Array (4 bytes)
• Entries Array (variable)
• Length of Options Array (4 bytes)
• Options Array (variable)

Implementations

impl<T: AsRef<[u8]>> Packet<T>

pub const fn new_unchecked(buffer: T) -> Packet<T>

Creates a new unchecked Packet.

Arguments

• buffer - A buffer containing the packet data.

Returns

• Packet - A new Packet instance.

pub fn new_checked(buffer: T) -> Result<Packet<T>>

Creates a new checked Packet.

Arguments

• buffer - A buffer containing the packet data.

Returns

• Result<Packet> - A new Packet instance if the buffer is valid.

pub fn check_len(&self) -> Result<()>

Checks the length of the packet.

Returns

• Result<()> - Ok if the length is valid, otherwise an error.

pub fn into_inner(self) -> T

Returns the inner buffer.

Returns

• T - The inner buffer.

pub fn as_slice(&self) -> &[u8]

Returns a reference to the inner buffer.

Returns

• &[u8] - A reference to the buffer.

pub fn flags(&self) -> u8

Returns the Flags byte

Returns

• u8 - The Flags byte of the packet

pub fn reserved(&self) -> u32

Returns the Reserved field (3 bytes, should be 0x000000)

Returns

• u32 - The Reserved field (only uses lower 24 bits)

pub fn entries_length(&self) -> usize

Returns the Length of Entries Array (4 bytes)

Returns

• usize - The length of the entries array in bytes

pub fn entries_array(&self) -> &[u8]

Returns the Entries Array

Returns

• &[u8] - A slice containing the entries array

pub fn options_length(&self) -> usize

Returns the Length of Options Array (4 bytes)

Returns

• usize - The length of the options array in bytes

pub fn options_array(&self) -> &[u8]

Returns the Options Array

Returns

• &[u8] - A slice containing the options array

pub fn total_length(&self) -> usize

Get the total packet length

Returns

• usize - The total length of the packet

impl<T: AsRef<[u8]> + AsMut<[u8]>> Packet<T>

pub fn set_flags(&mut self, flags: u8)

Sets the Flags byte

Arguments

• flags - The flags byte to set

pub fn set_reserved(&mut self, reserved: u32)

Sets the Reserved field (3 bytes, should be 0x000000)

Arguments

• reserved - The reserved value (only lower 24 bits used)

pub fn set_entries_length(&mut self, length: u32)

Sets the Length of Entries Array (4 bytes)

Arguments

• length - The length of the entries array in bytes

pub fn entries_array_mut(&mut self) -> &mut [u8]

Returns a mutable slice to the Entries Array

Returns

• &mut [u8] - A mutable slice to write entries data

pub fn set_options_length(&mut self, length: u32)

Sets the Length of Options Array (4 bytes)

Arguments

• length - The length of the options array in bytes

pub fn options_array_mut(&mut self) -> &mut [u8]

Returns a mutable slice to the Options Array

Returns

• &mut [u8] - A mutable slice to write options data

Trait Implementations

impl<T: Clone + AsRef<[u8]>> Clone for Packet<T>

fn clone(&self) -> Packet<T>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T: Debug + AsRef<[u8]>> Debug for Packet<T>

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

Formats the value using the given formatter.

impl<T: AsRef<[u8]>> Display for Packet<T>

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

Formats the value using the given formatter.

impl<T: PartialEq + AsRef<[u8]>> PartialEq for Packet<T>

fn eq(&self, other: &Packet<T>) -> 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.
