Enum ClassSet

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

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)

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

BinaryOp(ClassSetBinaryOp)

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

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

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.

fn drop(&mut self)

Executes the destructor for this type.

impl PartialEq for ClassSet

fn eq(&self, other: &ClassSet) -> 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 Eq for ClassSet

impl StructuralPartialEq for ClassSet

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
