Implementations

impl Parser

pub fn new(s: String) -> Parser

Constructor.

pub fn new_with_config(s: String, config: Config) -> Parser

Constructor with config.

pub fn config(&self) -> &Config

Get config reference.

pub fn input(&self) -> &str

Get input string at current position.

pub fn input_len(&self) -> usize

Return remaining input length.

pub fn pos(&self) -> usize

Return parser cusor position.

pub fn pos_add(&mut self, pos: usize)

Move cursor position forward.

pub fn line(&self) -> usize

Return line number.

pub fn line_add(&self, len: usize)

Add len to line number.

pub fn column_add(&self, num: usize)

Add chars to column.

pub fn column_set_from(&self, l: &str)

Set chars to column from last linefeed.

pub fn save_token(&mut self, token: Token)

Save token to saved.

pub fn load_token(&mut self) -> Option<Token>

Load token from saved.

pub fn peek_token(&mut self) -> Result<Token, YangError>

Get a token and save it.

pub fn get_token(&mut self) -> Result<Token, YangError>

Get a token except whitespace and comment.

pub fn get_single_token(&mut self) -> Result<(Token, usize), YangError>

Get a single token and position.

pub fn parse_yang(&mut self) -> Result<YangStmt, YangError>

Entry point of YANG parser. An input and a config has to be set. It will return a module or submodule statement.

pub fn parse_yang_from_string( s: String, config: Config, ) -> Result<YangStmt, Error>

Parse string as an input, and return YangStmt. Encapsulate YangError into io::Error.
