Struct LookupKey 

pub struct LookupKey(/* private fields */);

A keyed lookup value: the lowercase-hex HMAC of a domain-separated message.

Contains no plaintext and is safe to persist, but is still sensitive (it is the database lookup index). Compare lookup keys with LookupKey::ct_eq, not ==, when the comparison could be timing-attacked.

Implementations

impl LookupKey

pub fn as_str(&self) -> &str

Borrow the hex digest.

pub fn ct_eq(&self, other: &LookupKey) -> bool

Constant-time equality over the hex bytes (RFC-004; service parity with hmac_hex_eq). Length is allowed to leak: lookup keys are fixed-width.

Trait Implementations

impl Clone for LookupKey

fn clone(&self) -> LookupKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LookupKey

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

Formats the value using the given formatter.

impl Eq for LookupKey

impl Hash for LookupKey

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 PartialEq for LookupKey

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