Struct DatabaseId

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

Database ID is a locally public random byte array that can be used by the apps using this library to identify the database file. For example, if the app stores passwords externally (e.g. fingerprint biometric) it can do so under the DATABASE_ID as key. Note that the RepositoryId could - in theory - also be used for this purpose, but in case the database IDs are leaked to an adversary without the actual database files, the adversary will not be able to link the DATABASE_ID to a corresponding repository. For that reason database IDs may be preferable.

Implementations

impl DatabaseId

pub const SIZE: usize = 16usize

Trait Implementations

impl AsRef<[u8]> for DatabaseId

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

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

impl Clone for DatabaseId

fn clone(&self) -> DatabaseId

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for DatabaseId

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

Formats the value using the given formatter.

impl Display for DatabaseId

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

Formats the value using the given formatter.

impl Distribution<DatabaseId> for Standard

fn sample<R: Rng + ?Sized>(&self, rng: &mut R) -> DatabaseId

Generate a random value of T, using rng as the source of randomness.

fn sample_iter<R>(self, rng: R) -> DistIter<Self, R, T>

where R: Rng, Self: Sized,

Create an iterator that generates random values of T, using rng as the source of randomness.

fn map<F, S>(self, func: F) -> DistMap<Self, F, T, S>

where F: Fn(T) -> S, Self: Sized,

Create a distribution of values of ‘S’ by mapping the output of Self through the closure F

impl From<[u8; 16]> for DatabaseId

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

Converts to this type from the input type.

impl Hash for DatabaseId

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 LowerHex for DatabaseId

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

Formats the value using the given formatter.

impl Ord for DatabaseId

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

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

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

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 TryFrom<&[u8]> for DatabaseId

type Error = TryFromSliceError

The type returned in the event of a conversion error.

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

Performs the conversion.
