Struct serde_lexpr::parse::Options

pub struct Options { /* fields omitted */ }

Various options to influence parser behavior.

Methods

impl Options

pub fn new() -> Options

Construct an empty set of options.

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

pub fn elisp() -> Options

Construct a set of options suitable for parsing Emacs Lisp.

pub fn with_keyword_syntax(self, syntax: KeywordSyntax) -> Options

Add syntax to the recognized keyword syntaxes.

pub fn with_keyword_syntaxes<I, T>(self, styles: I) -> Options where
    I: IntoIterator<Item = T>,
    T: Borrow<KeywordSyntax>, 

Set the recognized keyword syntaxes.

pub fn with_nil_symbol(self, treatment: NilSymbol) -> Options

Choose how to parse the nil symbol.

pub fn with_t_symbol(self, treatment: TSymbol) -> Options

Choose how to parse the t symbol.

pub fn with_brackets(self, treatment: Brackets) -> Options

Choose how to handle brackets.

pub fn with_string_syntax(self, syntax: StringSyntax) -> Options

Choose the accepted string syntax.

pub fn with_char_syntax(self, syntax: CharSyntax) -> Options

Choose the accepted character syntax.

pub fn keyword_syntax(self, syntax: KeywordSyntax) -> bool

Check wether a keyword syntax 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.

pub fn brackets(self) -> Brackets

Query the way brackets are handled.

pub fn string_syntax(self) -> StringSyntax

Query the accepted string syntax.

pub fn char_syntax(self) -> CharSyntax

Query the accepted character syntax.

Trait Implementations

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 Copy for Options

impl Debug for Options

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

Formats the value using the given formatter.

impl Default for Options

fn default() -> Options

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.
• Brackets are treated just like parentheses, i.e. indicating a list.
