Enum regex_syntax::ast::ClassSetBinaryOpKind

pub enum ClassSetBinaryOpKind {
    Intersection,
    Difference,
    SymmetricDifference,
}

The type of a Unicode character class set operation.

Note that this doesn’t explicitly represent union since there is no explicit union operator. Concatenation inside a character class corresponds to the union operation.

Variants

Intersection

The intersection of two sets, e.g., \pN&&[a-z].

Difference

The difference of two sets, e.g., \pN--[0-9].

SymmetricDifference

The symmetric difference of two sets. The symmetric difference is the set of elements belonging to one but not both sets. e.g., [\pL~~[:ascii:]].

Trait Implementations

impl Clone for ClassSetBinaryOpKind

fn clone(&self) -> ClassSetBinaryOpKind

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ClassSetBinaryOpKind

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

Formats the value using the given formatter.

impl PartialEq for ClassSetBinaryOpKind

fn eq(&self, other: &ClassSetBinaryOpKind) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
