Enum Dissat

pub enum Dissat {
    None,
    Unique,
    Unknown,
}

Whether the fragment has a dissatisfaction, and if so, whether it is unique. Affects both correctness and malleability-freeness, since we assume 3rd parties are able to produce dissatisfactions for all fragments.

Variants

None

Fragment has no dissatisfactions and will abort given non-satisfying input.

Unique

Fragment has a unique dissatisfaction, which is always available, and will push 0 given this dissatisfaction as input. The combination of Dissat::Unique and Input::Zero implies that a fragment is impossible to satisfy (is a 0 or equivalent).

Unknown

No assumptions may be made about dissatisfying this fragment. This does not necessarily mean that there are multiple dissatisfactions; there may be none, or none that are always available (e.g. for a pk_h the key preimage may not be available).

Trait Implementations

impl Clone for Dissat

fn clone(&self) -> Dissat

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Dissat

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

Formats the value using the given formatter.

impl Hash for Dissat

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 Ord for Dissat

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

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

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