Struct Header 

pub struct Header {
    pub credit_charge: CreditCharge,
    pub status: NtStatus,
    pub command: Command,
    pub credits: u16,
    pub flags: HeaderFlags,
    pub next_command: u32,
    pub message_id: MessageId,
    pub tree_id: Option<TreeId>,
    pub async_id: Option<u64>,
    pub session_id: SessionId,
    pub signature: [u8; 16],
}

SMB2 packet header (64 bytes).

Contains both sync and async variants. The flags field determines which interpretation of bytes 32-39 is correct.

Fields

credit_charge: CreditCharge

Number of credits charged for this request.

status: NtStatus

In responses: NtStatus. In requests before SMB 3.x: Reserved. In requests for SMB 3.x: ChannelSequence (u16) + Reserved (u16).

command: Command

The command code for this packet.

credits: u16

In requests: credits requested. In responses: credits granted.

flags: HeaderFlags

Flags indicating how to process the operation.

next_command: u32

Offset to the next command in a compound chain (0 = last/only).

message_id: MessageId

Unique message identifier for request/response correlation.

tree_id: Option<TreeId>

Sync-only: tree identifier. None if async.

async_id: Option<u64>

Async-only: async identifier. None if sync.

session_id: SessionId

Session identifier.

signature: [u8; 16]

16-byte message signature.

Implementations

impl Header

pub const STRUCTURE_SIZE: u16 = 64

pub const SIZE: usize = 64

Total header size in bytes.

pub fn new_request(command: Command) -> Self

Create a new request header for a given command.

pub fn is_response(&self) -> bool

Is this a response (vs request)?

Trait Implementations

impl Clone for Header

fn clone(&self) -> Header

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Header

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

Formats the value using the given formatter.

impl Eq for Header

impl Pack for Header

fn pack(&self, cursor: &mut WriteCursor)

Write this value into the cursor.

impl PartialEq for Header

fn eq(&self, other: &Header) -> 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.

impl StructuralPartialEq for Header

impl Unpack for Header

fn unpack(cursor: &mut ReadCursor<'_>) -> Result<Self>

Read a value from the cursor, advancing its position.
