Struct SendmeTag 

pub struct SendmeTag {
    len: NonZeroU8,
    tag: CtByteArray<20>,
}

An authentication tag to use for circuit-level SENDME messages.

It is either a 20-byte tag (used with Tor1 encryption), or a 16-byte tag (used with CGO encryption).

Fields

len: NonZeroU8

The number of bytes present in the tag. Always equal to 16 or 20.

We use a NonZeroU8 here so Rust can use its niche optimization.

tag: CtByteArray<20>

The actual contents of the tag.

Tags above 20 bytes long are always an error.

Unused bytes are always set to zero, so we can derive PartialEq.

Trait Implementations

impl AsRef<[u8]> for SendmeTag

fn as_ref(&self) -> &[u8]

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for SendmeTag

fn clone(&self) -> SendmeTag

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SendmeTag

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

Formats the value using the given formatter.

impl From<[u8; 16]> for SendmeTag

fn from(value: [u8; 16]) -> Self

Converts to this type from the input type.

impl From<[u8; 20]> for SendmeTag

fn from(value: [u8; 20]) -> Self

Converts to this type from the input type.

impl From<SendmeTag> for Sendme

fn from(value: SendmeTag) -> Self

Converts to this type from the input type.

impl HasMemoryCostStructural for SendmeTag

fn indirect_memory_cost(&self, et: EnabledToken) -> usize

Memory cost of data stored out-of-line

impl PartialEq for SendmeTag

fn eq(&self, other: &SendmeTag) -> 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<'a> TryFrom<&'a [u8]> for SendmeTag

type Error = InvalidSendmeTag

The type returned in the event of a conversion error.

fn try_from(value: &'a [u8]) -> Result<Self, Self::Error>

Performs the conversion.
