Enum PatternObject

pub enum PatternObject {
    Any,
    Start,
    End,
    String(String),
    Quantifier(Quantifier, Box<PatternObject>),
    Escaped(char),
    Class(Class),

A single object of a Lua pattern.

Variants

Any

Match any character (.).

Start

Match the start of the string (^).

End

Match the end of the string ($).

String(String)

A sequence of characters to match literally (eg. Hello, World!).

Quantifier(Quantifier, Box<PatternObject>)

A PatternObject followed by a Quantifier (eg. a?, .*).

Escaped(char)

An escaped character to match literally (eg. %%).

Class(Class)

A character class (eg. %w, %L).

CaptureRef(u8)

A reference to a previous capture group (eg. %1).

Balanced(char, char)

A balanced pattern (eg. %bxy). Matches all characters starting at x until the corresponding y.

Frontier(bool, Vec<SetPatternObject>)

A frontier pattern (eg. %f[a-z]). Matches if the following character matches the set and the previous character does not match the set. The bool indicated whether the set is inverted.

Capture(u8, Pattern)

A capture group with a numeric ID and the contained Pattern (eg. (a)).

Set(bool, Vec<SetPatternObject>)

A set of SetPatternObjects (eg. [a-z_%u], [^a-z_%u]), the bool specifies whether the set is inverted. If the set is not inverted, it matches if any of the contained entries matches. Otherwise, it matches if none of the contained entries match.

Trait Implementations

impl Clone for PatternObject

fn clone(&self) -> PatternObject

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PatternObject

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

Formats the value using the given formatter.

impl PartialEq for PatternObject

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