Struct fadroma::scrt::vk::ViewingKey
source · pub struct ViewingKey(pub String);
Expand description
Represents a viewing key string which is provided as unverified input to a query.
PartialEq
is intentionally not implemented on this type in order to prevent
from using it to check viewing keys that way. You should convert to ViewingKeyHashed
(using ViewingKey::to_hashed
) and then call ViewingKeyHashed::check
which performs
a specialized constant time equality comparison. ViewingKey::check
and
ViewingKey::check_hashed
are also provided for convenience.

Implementations§
source§impl ViewingKey
impl ViewingKey
pub fn new(env: &Env, info: &MessageInfo, seed: &[u8], entropy: &[u8]) -> Self
sourcepub fn to_hashed(&self) -> ViewingKeyHashed
pub fn to_hashed(&self) -> ViewingKeyHashed
Converts the viewing key to SHA-256 hash representation.
pub fn as_bytes(&self) -> &[u8] ⓘ
sourcepub fn check(&self, other: &ViewingKey) -> bool
pub fn check(&self, other: &ViewingKey) -> bool
Converts both self
and other
to ViewingKeyHashed
and compares them for equality using a constant time function.
sourcepub fn check_hashed(&self, hashed: &ViewingKeyHashed) -> bool
pub fn check_hashed(&self, hashed: &ViewingKeyHashed) -> bool
Converts self
to ViewingKeyHashed
and compares
it to other
for equality using a constant time function.

source§fn size_hint(&self) -> usize
fn size_hint(&self) -> usize
The size in bytes of the particular instance when
converted to its byte respresentation. While it’s
preferred that this method returns an exact size
(or at least a bigger estimation) it’s not an error
to return an incorrect number. The penalty for doing
so is potentially incurring unnecessary re-allocations.
