Struct erl_tokenize::tokens::CommentToken

pub struct CommentToken { /* fields omitted */ }

Comment token.

Examples

use erl_tokenize::Position;
use erl_tokenize::tokens::CommentToken;

let pos = Position::new();

// Ok
assert_eq!(CommentToken::from_text("%", pos.clone()).unwrap().value(), "");
assert_eq!(CommentToken::from_text("%% foo ", pos.clone()).unwrap().value(), "% foo ");

// Err
assert!(CommentToken::from_text("  % foo", pos.clone()).is_err());

Methods

impl CommentToken

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

Makes a new CommentToken instance from the value.

Examples

use erl_tokenize::Position;
use erl_tokenize::tokens::CommentToken;

let pos = Position::new();
assert_eq!(CommentToken::from_value("foo", pos.clone()).unwrap().text(), "%foo");

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

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

pub fn value(&self) -> &str

Returns the value of this token.

Examples

use erl_tokenize::Position;
use erl_tokenize::tokens::CommentToken;

let pos = Position::new();

assert_eq!(CommentToken::from_text("%", pos.clone()).unwrap().value(), "");
assert_eq!(CommentToken::from_text("%% foo ", pos.clone()).unwrap().value(), "% foo ");

pub fn text(&self) -> &str

Returns the original textual representation of this token.

Examples

use erl_tokenize::Position;
use erl_tokenize::tokens::CommentToken;

let pos = Position::new();

assert_eq!(CommentToken::from_text("%", pos.clone()).unwrap().text(), "%");
assert_eq!(CommentToken::from_text("%% foo ", pos.clone()).unwrap().text(), "%% foo ");
