Enum Soundness 

pub enum Soundness {
    MayOver,
    MustUnder,
    Exact,
}

Soundness regime of a dataflow primitive.

Rules with zero-FP precision contracts MUST only compose primitives whose marker is Exact, or MayOver primitives gated by an explicit sanitizer filter downstream.

Variants

MayOver

Over-approximates: may report taint where none exists. Safe for recall-driven rules paired with a downstream filter.

MustUnder

Under-approximates: may miss taint that exists. Safe only when the rule semantics explicitly accept false negatives.

Exact

Exact: reports taint iff taint exists on the given CFG. No false positives, no false negatives, given a correct input AST.

Implementations

impl Soundness

pub const fn join(self, other: Soundness) -> Soundness

Conservative join of two soundness markers.

The join is the least precise soundness that soundly describes the composition of two primitives.

Trait Implementations

impl Clone for Soundness

fn clone(&self) -> Soundness

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Soundness

impl Debug for Soundness

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Soundness

fn deserialize<__D>( __deserializer: __D, ) -> Result<Soundness, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for Soundness

impl Hash for Soundness

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 PartialEq for Soundness

fn eq(&self, other: &Soundness) -> 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 Serialize for Soundness

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.
