Struct Threshold

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

A valid threshold for the identity Doc.

It can only be constructed via Threshold::new or Threshold::MIN.

Implementations

impl Threshold

pub const MIN: Threshold

A threshold of 1.

pub fn new(t: usize, delegates: &Delegates) -> Result<Threshold, ThresholdError>

Construct the Threshold by checking that t is not greater than MAX_DELEGATES, that it does not exceed the number of delegates, and is non-zero.

Trait Implementations

impl AsRef<NonZero<usize>> for Threshold

fn as_ref(&self) -> &NonZero<usize>

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

impl Clone for Threshold

fn clone(&self) -> Threshold

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Threshold

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

Formats the value using the given formatter.

impl Display for Threshold

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

Formats the value using the given formatter.

impl Hash for Threshold

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

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 Threshold

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

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

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

impl Serialize for Threshold

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for Threshold
