Represents various unit expressions within a program.

Variants

Primitives

Primitive unit expression with specified data type and repetition type.

Fields

data_type: DataType

repetition: PositiveReferenceType

CapturingGroup

Capturing group unit expression with a group number and range.

Fields

group_number: u64

range: (PositiveReferenceType, PositiveReferenceType)

NonCapturingGroup

Non-capturing group unit expression with nested expressions and repetition type.

Fields

nest_exp: Vec<UnitExpression>

repetition: PositiveReferenceType

Eof

Represents the end of the file in the program.

Trait Implementations

impl Clone for UnitExpression

fn clone(&self) -> UnitExpression

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for UnitExpression

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

Formats the value using the given formatter.

impl PartialEq for UnitExpression

fn eq(&self, other: &UnitExpression) -> 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.
