Enum KeySecurity 

#[non_exhaustive]
#[repr(u8)]
pub enum KeySecurity {
    Weak = 0,
    Strong = 1,
    Untracked = 2,
}

Available on crate feature nip49 only.

Author-declared key-security level, baked into the ciphertext as AEAD additional-authenticated-data so it cannot be forged after the fact.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Weak = 0

0x00 — author admits the key has been handled insecurely (cut-and-pasted, kept in plaintext, etc.).

Strong = 1

0x01 — author asserts the key has only ever lived inside an encrypted container.

Untracked = 2

0x02 — author does not track this signal.

Implementations

impl KeySecurity

pub const fn from_byte(byte: u8) -> Result<Self, Nip49Error>

Round-trip from the u8 byte found on the wire.

Errors

Returns Nip49Error::InvalidKeySecurity for any byte outside 0x00..=0x02.

Trait Implementations

impl Clone for KeySecurity

fn clone(&self) -> KeySecurity

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for KeySecurity

impl Debug for KeySecurity

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

Formats the value using the given formatter.

impl Eq for KeySecurity

impl Hash for KeySecurity

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 Ord for KeySecurity

fn cmp(&self, other: &KeySecurity) -> 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 KeySecurity

fn eq(&self, other: &KeySecurity) -> 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 KeySecurity

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