Struct Digits

pub struct Digits { /* private fields */ }

Represents the number of digits in OTPs.

Implementations

impl Digits

pub const MIN: Self

The minimum Self value.

pub const MAX: Self

The maximum Self value.

pub const DEFAULT: Self

The default Self value.

pub const fn new(value: u8) -> Result<Self, Error>

Constructs Self, if possible.

Errors

See check for more information.

pub const fn new_ok(value: u8) -> Option<Self>

Similar to new, but the error is discarded.

pub const fn check(value: u8) -> Result<(), Error>

Checks if the provided value is valid for Self.

Errors

Returns Error if the given value is less than MIN or greater than MAX.

pub const unsafe fn new_unchecked(value: u8) -> Self

Constructs Self without checking the given value.

Safety

The value must be greater than or equal to MIN and less than or equal to MAX.

This invariant can be checked using check.

pub const fn count(self) -> usize

Returns the value wrapped in Self as usize.

pub const fn get(self) -> u8

Returns the value wrapped in Self.

pub const fn power(self) -> u32

Raises 10 to the power of the value wrapped in Self.

pub fn string(self, code: u32) -> String

Formats the given code, padding it to the length returned from count.

Trait Implementations

impl Clone for Digits

fn clone(&self) -> Digits

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Digits

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

Formats the value using the given formatter.

impl Default for Digits

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Digits

Available on crate feature serde only.

fn deserialize<D: Deserializer<'de>>(deserializer: D) -> Result<Self, D::Error>

Deserialize this value from the given Serde deserializer.

impl Display for Digits

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

Formats the value using the given formatter.

impl From<Digits> for u8

fn from(digits: Digits) -> Self

Converts to this type from the input type.

impl FromStr for Digits

type Err = ParseError

The associated error which can be returned from parsing.

fn from_str(string: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl Hash for Digits

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 Digits

fn eq(&self, other: &Digits) -> 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 Serialize for Digits

Available on crate feature serde only.

fn serialize<S: Serializer>(&self, serializer: S) -> Result<S::Ok, S::Error>

Serialize this value into the given Serde serializer.

impl TryFrom<u8> for Digits

type Error = Error

The type returned in the event of a conversion error.

fn try_from(value: u8) -> Result<Self, Self::Error>

Performs the conversion.
