Implementations

impl NonFinalNode

pub fn reason(&self) -> String

Parsing can fail when a NonFinalNode is not converted into a FinalNode. This function returns an explanation to show to the user.

pub fn unwrap_open_class(self) -> (bool, Vec<ClassItem>)

Returns the contents of this NonFinalNode::OpenClass(..). Panics if this is a different enum variant.

pub fn unwrap_open_alt(self) -> Vec<FinalNode>

Returns the contents of this NonFinalNode::OpenAlt(..). Panics if this is a different enum variant.

pub fn unwrap_repeat_min(self) -> String

Returns the contents of this NonFinalNode::RepeatMin(..). Panics if this is a different enum variant.

pub fn unwrap_repeat_max(self) -> (String, String)

Returns the contents of this NonFinalNode::RepeatMax(..). Panics if this is a different enum variant.

Trait Implementations

impl Clone for NonFinalNode

fn clone(&self) -> NonFinalNode

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for NonFinalNode

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

Formats the value using the given formatter.

impl PartialEq for NonFinalNode

fn eq(&self, other: &NonFinalNode) -> 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 PartialOrd for NonFinalNode

fn partial_cmp(&self, other: &NonFinalNode) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
