Enum Reversibility 

pub enum Reversibility {
    Reversible,
    Costly,
    Irreversible,
}

How recoverable a tool’s effect is. Orthogonal to risk tier.

Default is Reversibility::Irreversible — deny-by-default: an unclassified tool is treated as the most consequential until proven otherwise.

Variants

Reversible

Effects can be undone freely (reads, idempotent no-ops).

Costly

Recoverable, but undoing costs real money / time (spend, large compute).

Irreversible

Cannot be undone (deletes, deploys, payments, external sends).

Implementations

impl Reversibility

pub fn as_str(self) -> &'static str

Stable snake_case wire label.

pub fn parse(value: &str) -> Self

Parse from a stored string, defaulting unknown → Irreversible (deny-by-default). Never fails — an unparseable value is the most restrictive rung, which is the safe direction.

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<'de> Deserialize<'de> for Reversibility

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for Reversibility

impl FromStr for Reversibility

type Err = Infallible

The associated error which can be returned from parsing.

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

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

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.

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

Equality operator ==.

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