Enum Reversibility 

pub enum Reversibility {
    None,
    Trivial,
    Recoverable,
    Effortful,
    Irreversible,
}

How hard the effect is to undo (v1.4 §2.3). Environment-dependent cases resolve worst-case (HP-8).

Variants

None

Trait Implementations

impl Clone for Reversibility

fn clone(&self) -> Reversibility

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Reversibility

impl Debug for Reversibility

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

Formats the value using the given formatter.

impl Default for Reversibility

fn default() -> Reversibility

Returns the “default value” for a type.

impl Eq for Reversibility

impl FacetTerm for Reversibility

fn all() -> &'static [Self]

Every term, in declaration order (for ordinals, least-severe first).

fn as_str(self) -> &'static str

The term’s canonical TOML spelling.

fn from_term(s: &str) -> Option<Self>

Parse a term from its TOML spelling.

fn hazard() -> Self

The term a level is LEAST likely to admit — the one Capability::worst carries on this axis.

impl Hash for Reversibility

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 Reversibility

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

fn eq(&self, other: &Reversibility) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.

impl PartialOrd for Reversibility

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