Struct OptionList 

pub struct OptionList(/* private fields */);

A node in the syntax tree for OptionList

Implementations

impl OptionList

pub fn line(&self) -> usize

Get the line number (0-indexed) where this node starts.

pub fn column(&self) -> usize

Get the column number (0-indexed, in bytes) where this node starts.

pub fn line_col(&self) -> (usize, usize)

Get both line and column (0-indexed) where this node starts. Returns (line, column) where column is measured in bytes from the start of the line.

impl OptionList

pub fn options(&self) -> impl Iterator<Item = _Option> + '_

Returns an iterator over all option nodes in the options list.

pub fn find_option(&self, key: &str) -> Option<_Option>

Find an option node by key.

pub fn has_option(&self, key: &str) -> bool

Check if an option with the given key exists

pub fn get_option(&self, key: &str) -> Option<String>

Get the value of an option by key

Trait Implementations

impl Clone for OptionList

fn clone(&self) -> OptionList

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for OptionList

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

Formats the value using the given formatter.

impl Display for OptionList

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

Formats the value using the given formatter.

impl Hash for OptionList

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for OptionList

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