Struct Refinement 

pub struct Refinement {
    pub var_name: String,
    pub predicate: TLExpr,
}

Refinement: a logical predicate that refines a type.

Fields

var_name: String

Variable name being refined

predicate: TLExpr

Refinement predicate

Implementations

impl Refinement

pub fn new(var_name: impl Into<String>, predicate: TLExpr) -> Self

pub fn free_vars(&self) -> HashSet<String>

Get free variables in the refinement (excluding the refined variable)

pub fn substitute(&self, subst: &HashMap<String, Term>) -> Refinement

Substitute variables in the refinement

pub fn simplify(&self) -> Refinement

Simplify the refinement predicate

pub fn implies(&self, other: &Refinement) -> bool

Check if refinement implies another refinement

Trait Implementations

impl Clone for Refinement

fn clone(&self) -> Refinement

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Refinement

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Refinement

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Refinement

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

Formats the value using the given formatter.

impl PartialEq for Refinement

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

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
