Struct erl_tokenize::tokens::StringToken

pub struct StringToken { /* fields omitted */ }

String token.

Examples

use erl_tokenize::Position;
use erl_tokenize::tokens::StringToken;

let pos = Position::new();

// Ok
assert_eq!(StringToken::from_text(r#""foo""#, pos.clone()).unwrap().value(), "foo");
assert_eq!(StringToken::from_text(r#""foo"  "#, pos.clone()).unwrap().value(), "foo");
assert_eq!(StringToken::from_text(r#""f\x6Fo""#, pos.clone()).unwrap().value(), "foo");

// Err
assert!(StringToken::from_text(r#"  "foo""#, pos.clone()).is_err());

Methods

impl StringToken

fn from_value(value: &str, pos: Position) -> Self

Makes a new StringToken instance from the value.

Examples

use erl_tokenize::Position;
use erl_tokenize::tokens::StringToken;

let pos = Position::new();
assert_eq!(StringToken::from_value("foo", pos.clone()).text(), r#""foo""#);

fn from_text(text: &str, pos: Position) -> Result<Self>

Tries to convert from any prefixes of the text to a StringToken.

fn value(&self) -> &str

Returns the value of this token.

Examples

use erl_tokenize::Position;
use erl_tokenize::tokens::StringToken;

let pos = Position::new();

assert_eq!(StringToken::from_text(r#""foo""#, pos.clone()).unwrap().value(), "foo");
assert_eq!(StringToken::from_text(r#""foo"  "#, pos.clone()).unwrap().value(), "foo");
assert_eq!(StringToken::from_text(r#""f\x6Fo""#, pos.clone()).unwrap().value(), "foo");

fn text(&self) -> &str

Returns the original textual representation of this token.

Examples

use erl_tokenize::Position;
use erl_tokenize::tokens::StringToken;

let pos = Position::new();

assert_eq!(StringToken::from_text(r#""foo""#, pos.clone()).unwrap().text(),
           r#""foo""#);
assert_eq!(StringToken::from_text(r#""foo"  "#, pos.clone()).unwrap().text(),
           r#""foo""#);
assert_eq!(StringToken::from_text(r#""f\x6Fo""#, pos.clone()).unwrap().text(),
           r#""f\x6Fo""#);
