Enum regex_syntax::ast::ClassSet

[−] Show declaration

pub enum ClassSet {
    Item(ClassSetItem),
    BinaryOp(ClassSetBinaryOp),
}

[−] Expand description

A character class set.

This type corresponds to the internal structure of a bracketed character class. That is, every bracketed character is one of two types: a union of items (literals, ranges, other bracketed classes) or a tree of binary set operations.

Variants

Item(ClassSetItem)

[−] Expand description

An item, which can be a single literal, range, nested character class or a union of items.

BinaryOp(ClassSetBinaryOp)

[−] Expand description

A single binary operation (i.e., &&, -- or ~~).

Implementations

impl ClassSet[−]

pub fn union(ast: ClassSetUnion) -> ClassSet[−]

Build a set from a union.

pub fn span(&self) -> &Span[−]

Return the span of this character class set.

Trait Implementations

impl Clone for ClassSet[+]

[+] Show hidden undocumented items

fn clone(&self) -> ClassSet[−]

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)[−]

Performs copy-assignment from source.

impl Debug for ClassSet[+]

[+] Show hidden undocumented items

fn fmt(&self, f: &mut Formatter) -> Result[−]

Formats the value using the given formatter.

impl Drop for ClassSet[+]

A custom Drop impl is used for ClassSet such that it uses constant stack space but heap space proportional to the depth of the ClassSet.

[+] Show hidden undocumented items

fn drop(&mut self)[−]

Executes the destructor for this type.

impl Eq for ClassSet

impl PartialEq<ClassSet> for ClassSet[+]

[+] Show hidden undocumented items

fn eq(&self, other: &ClassSet) -> bool[−]

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

fn ne(&self, other: &ClassSet) -> bool[−]

This method tests for !=.
