ParserConfig

Struct ParserConfig 

Source
pub struct ParserConfig {
    pub comments: bool,
}
Expand description

ParserConfig for reading Links Notation documents.

Provides configuration options for controlling how a document is read.

Fields§

§comments: bool

If true, a # written where a line or a token starts opens a comment that runs to the end of the line (default: true)

Implementations§

Source§

impl ParserConfig

Source

pub fn new() -> Self

Create a new ParserConfig with default values

§Examples
use links_notation::ParserConfig;

assert!(ParserConfig::new().comments);
Source

pub fn without_comments() -> Self

Create a ParserConfig that reads # as an ordinary reference character, the way documents written before comments existed were read.

§Examples
use links_notation::{parse_lino_with_config, ParserConfig};

let parsed = parse_lino_with_config("# a b", &ParserConfig::without_comments()).unwrap();
assert_eq!(format!("{}", parsed), "((# a b))");

Source

pub fn with_comments(comments: bool) -> Self

Create a ParserConfig that turns comments on or off

§Examples
use links_notation::ParserConfig;

assert_eq!(ParserConfig::with_comments(false), ParserConfig::without_comments());
