Struct FrameHeader 

pub struct FrameHeader {
    pub magic: [u8; 2],
    pub version: u8,
    pub flags: u8,
    pub profile_id: u8,
    pub key_id: u8,

Plaintext wire header authenticated as AEAD AAD.

Fields

magic: [u8; 2]

Draft magic marker.

version: u8

Protocol version.

flags: u8

Frame flags bitfield.

profile_id: u8

Cryptographic profile identifier.

key_id: u8

Active traffic-key identifier.

stream_id: u32

Logical stream identifier.

seq: u64

Sequence number per stream/direction/key.

ct_len: u32

Ciphertext length in bytes.

Implementations

impl FrameHeader

pub fn new( flags: u8, profile_id: u8, key_id: u8, stream_id: u32, seq: u64, ct_len: u32, ) -> Self

Creates a header value for a frame.

pub fn encode(&self) -> [u8; 22]

Serializes header into fixed-width wire bytes.

pub fn decode(buf: &[u8]) -> Result<Self, CoreError>

Parses a fixed-width frame header from bytes.

pub fn validate_v0(&self) -> Result<(), CoreError>

Validates version/profile/flags according to Draft v0.

Trait Implementations

impl Clone for FrameHeader

fn clone(&self) -> FrameHeader

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FrameHeader

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

Formats the value using the given formatter.

impl PartialEq for FrameHeader

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