Trait Implementations

impl Clone for ExistentialPredicate

fn clone(&self) -> ExistentialPredicate

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ExistentialPredicate

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

Formats the value using the given formatter.

impl Default for ExistentialPredicate

fn default() -> ExistentialPredicate

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for ExistentialPredicate

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Drive for ExistentialPredicate

fn drive<V: Visitor>(&self, visitor: &mut V)

impl DriveMut for ExistentialPredicate

fn drive_mut<V: VisitorMut>(&mut self, visitor: &mut V)

impl<C: AstFormatter> FmtWithCtx<C> for ExistentialPredicate

fn fmt_with_ctx(&self, _ctx: &C) -> String

fn fmt_with_ctx_and_indent(&self, _tab: &str, _ctx: &C) -> String

fn with_ctx<'a>(&'a self, ctx: &'a C) -> impl Display + 'a

Returns a struct that implements Display. This allows the following:

impl Hash for ExistentialPredicate

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 ExistentialPredicate

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
