Struct CtByteArray 

pub struct CtByteArray<const N: usize>(/* private fields */);

A byte array of length N for which comparisons are performed in constant time.

Limitations

It is possible to avoid constant time comparisons here, just by using the as_ref() and as_mut() methods. They should therefore be approached with some caution.

(The decision to avoid implementing Deref/DerefMut is deliberate.)

Trait Implementations

impl<const N: usize> AsMut<[u8; N]> for CtByteArray<N>

fn as_mut(&mut self) -> &mut [u8; N]

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

impl<const N: usize> AsRef<[u8; N]> for CtByteArray<N>

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

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

impl<const N: usize> Clone for CtByteArray<N>

fn clone(&self) -> CtByteArray<N>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<const N: usize> ConstantTimeEq for CtByteArray<N>

fn ct_eq(&self, other: &Self) -> Choice

Determine if two items are equal.

fn ct_ne(&self, other: &Self) -> Choice

Determine if two items are NOT equal.

impl<const N: usize> Debug for CtByteArray<N>

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

Formats the value using the given formatter.

impl<const N: usize> From<[u8; N]> for CtByteArray<N>

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

Converts to this type from the input type.

impl<const N: usize> From<CtByteArray<N>> for [u8; N]

fn from(value: CtByteArray<N>) -> Self

Converts to this type from the input type.

impl<const N: usize> HasMemoryCostStructural for CtByteArray<N>

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

Memory cost of data stored out-of-line

impl<const N: usize> Hash for CtByteArray<N>

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<const N: usize> Ord for CtByteArray<N>

fn cmp(&self, other: &Self) -> 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<const N: usize> PartialEq for CtByteArray<N>

fn eq(&self, other: &Self) -> 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<const N: usize> PartialOrd for CtByteArray<N>

fn partial_cmp(&self, other: &Self) -> 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.

impl<const N: usize> Zeroize for CtByteArray<N>

fn zeroize(&mut self)

Zero out this object from memory using Rust intrinsics which ensure the zeroization operation is not “optimized away” by the compiler.

impl<const N: usize> Copy for CtByteArray<N>

impl<const N: usize> Eq for CtByteArray<N>
