Enum SortClosure 

pub enum SortClosure {
    Open,
    Closed(Vec<Arc<str>>),
}

Closure attribute on a Sort.

An open sort may be inhabited by any operation whose output head names this sort. A closed sort enumerates the exhaustive set of constructor operations, enabling pattern matching via Term::Case and exhaustiveness checking at theory-declaration time.

Variants

Open

Open sort: any operation with this output head may produce an inhabitant. No exhaustiveness check applies.

Closed(Vec<Arc<str>>)

Closed sort: the listed op names form the complete set of introduction forms. Pattern matches over this sort must cover every listed constructor exactly once.

Trait Implementations

impl Clone for SortClosure

fn clone(&self) -> SortClosure

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SortClosure

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

Formats the value using the given formatter.

impl Default for SortClosure

fn default() -> SortClosure

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for SortClosure

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for SortClosure

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 PartialEq for SortClosure

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for SortClosure
