Struct erl_tokenize::tokens::WhitespaceToken

pub struct WhitespaceToken { /* fields omitted */ }

Whitespace token.

Examples

use erl_tokenize::Position;
use erl_tokenize::tokens::WhitespaceToken;
use erl_tokenize::values::Whitespace;

let pos = Position::new();

// Ok
assert_eq!(WhitespaceToken::from_text(" ", pos.clone()).unwrap().value(), Whitespace::Space);
assert_eq!(WhitespaceToken::from_text("\t ", pos.clone()).unwrap().value(), Whitespace::Tab);

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

Methods

impl WhitespaceToken

pub fn from_value(value: Whitespace, pos: Position) -> Self

Makes a new WhitespaceToken instance from the value.

Examples

use erl_tokenize::Position;
use erl_tokenize::tokens::WhitespaceToken;
use erl_tokenize::values::Whitespace;

let pos = Position::new();
assert_eq!(WhitespaceToken::from_value(Whitespace::Space, pos.clone()).text(), " ");

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

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

pub fn value(&self) -> Whitespace

Returns the value of this token.

Examples

use erl_tokenize::Position;
use erl_tokenize::tokens::WhitespaceToken;
use erl_tokenize::values::Whitespace;

let pos = Position::new();

assert_eq!(WhitespaceToken::from_text(" ", pos.clone()).unwrap().value(),
           Whitespace::Space);
assert_eq!(WhitespaceToken::from_text("\t ", pos.clone()).unwrap().value(),
           Whitespace::Tab);

pub fn text(&self) -> &'static str

Returns the original textual representation of this token.

Examples

use erl_tokenize::Position;
use erl_tokenize::tokens::WhitespaceToken;

let pos = Position::new();

assert_eq!(WhitespaceToken::from_text(" ", pos.clone()).unwrap().text(), " ");
assert_eq!(WhitespaceToken::from_text("\t ", pos.clone()).unwrap().text(), "\t");
