Struct CryptoHeader

pub struct CryptoHeader { /* private fields */ }

The header used by CCMP and GCMP cryptographic encapsulation.

This currently does not support WEP and TKIP.

Implementations

impl CryptoHeader

pub const MAX_PN: u64 = 281_474_976_710_655u64

The largest representable packet number.

pub const MAX_KEY_ID: u8 = 3u8

The largest representable key ID.

pub fn new(packet_number: u64, key_id: u8) -> Option<Self>

Create a new CryptoHeader.

Returns Option::None if packet_number is larger than Self::MAX_PN or key_id is larger than Self::MAX_KEY_ID.

pub fn packet_number(&self) -> u64

Get the packet number as a u64.

This will return a number between 0 and including Self::MAX_PN.

pub fn key_id(&self) -> u8

Get the key ID.

This will return a number between 0 and including Self::MAX_KEY_ID.

Trait Implementations

impl Clone for CryptoHeader

fn clone(&self) -> CryptoHeader

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CryptoHeader

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

Formats the value using the given formatter.

impl Default for CryptoHeader

fn default() -> CryptoHeader

Returns the “default value” for a type.

impl Format for CryptoHeader

where [u8; 6]: Format,

fn format(&self, f: Formatter<'_>)

Writes the defmt representation of self to fmt.

impl Hash for CryptoHeader

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 MeasureWith<()> for CryptoHeader

fn measure_with(&self, _ctx: &()) -> usize

How large is Self, given the ctx?

impl Ord for CryptoHeader

fn cmp(&self, other: &CryptoHeader) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for CryptoHeader

fn eq(&self, other: &CryptoHeader) -> 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 PartialOrd for CryptoHeader

fn partial_cmp(&self, other: &CryptoHeader) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
