Enum BuiltinFunction 

#[non_exhaustive]
pub enum BuiltinFunction {
    HasParseFact,
    Size,
    IsEmpty,
    Contains,
    All,
    Exists,
    Matches,
}

Bounded built-in function.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

HasParseFact

Returns true when a named parse fact exists.

Size

Returns collection or string size.

IsEmpty

Returns true when a collection or string is empty.

Contains

Returns true when a collection or string contains a value.

All

Returns true when every boolean argument is true.

Exists

Returns true when any boolean argument is true.

Matches

Returns true when a bounded regex matches a string.

Trait Implementations

impl Clone for BuiltinFunction

fn clone(&self) -> BuiltinFunction

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BuiltinFunction

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for BuiltinFunction

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for BuiltinFunction

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for BuiltinFunction

impl Eq for BuiltinFunction
