Struct lexpr::parse::Options

pub struct Options { /* fields omitted */ }

Various options to influence parser behavior.

Methods

impl Options

pub fn new() -> Self

Construct an empty set of options.

This will recognize no keywords, and parse nil and t as regular symbols.

pub fn elisp() -> Self

Construct a set of options suitable for parsing Emacs Lisp.

pub fn with_keyword_style(self, style: KeywordStyle) -> Self

Add style to the recognized keyword styles.

pub fn with_keyword_styles<I, T>(self, styles: I) -> Self where
    I: IntoIterator<Item = T>,
    T: Borrow<KeywordStyle>, 

Set the recognized keyword styles.

pub fn with_nil_symbol(self, handling: NilSymbol) -> Self

Choose how to parse the nil symbol.

pub fn with_t_symbol(self, handling: TSymbol) -> Self

Choose how to parse the t symbol.

pub fn keyword_style(&self, style: KeywordStyle) -> bool

Check wether a keyword style is enabled.

pub fn nil_symbol(&self) -> NilSymbol

Query the way the nil symbol is handled.

pub fn t_symbol(&self) -> TSymbol

Query the way the t symbol is handled.

Trait Implementations

impl Default for Options

fn default() -> Self

Construct a default set of options. This corresponds most closely to the Scheme dialect of S-expressions:

• The identifiers nil and t are treated as regular symbols.
• Only octothorpe keywords are recognized.

impl Clone for Options

fn clone(&self) -> Options

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Options

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

Formats the value using the given formatter.
