Enum Safety 

pub enum Safety {
    FormatOnly,
    BehaviorPreserving,
    ScopeLocal,
    SurfaceChanging,
    CapabilityChanging,
    NeedsHuman,
}

How risky a rule’s fix is, mapped onto Burin’s edit-safety taxonomy. Ordered least → most dangerous; the codemod runner auto-applies only the two safest tiers (see Safety::applicability).

Variants

FormatOnly

Whitespace / formatting only.

BehaviorPreserving

Semantics-preserving rewrite.

ScopeLocal

Changes behavior, but only within the matched scope. Default — conservative, so an undeclared codemod does not silently auto-apply.

SurfaceChanging

Changes an externally-visible surface (a signature, an export).

CapabilityChanging

Changes capabilities / effects (I/O, permissions).

NeedsHuman

Always requires a human in the loop.

Implementations

impl Safety

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

The stable kebab-case name (the inverse of the Deserialize rename), used for diagnostics and JSON surfaces.

pub fn applicability(self) -> Applicability

The applicability tier this safety level maps to. format-only and behavior-preserving are machine-applicable; everything riskier is a suggestion.

pub fn is_auto_applicable(self) -> bool

True when the runner may auto-apply this rule’s fix without an explicit opt-in.

Trait Implementations

impl Clone for Safety

fn clone(&self) -> Safety

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Safety

impl Debug for Safety

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

Formats the value using the given formatter.

impl Default for Safety

fn default() -> Safety

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Safety

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for Safety

impl Ord for Safety

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

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

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