Implementations

impl TokenBlock

pub fn current(&self) -> Result<&str, RuntimeError>

返回当前 token；若已读完则返回 Error。

pub fn skip_token(&mut self, token: &str) -> Result<(), RuntimeError>

pub fn advance(&mut self) -> Result<String, RuntimeError>

pub fn skip(&mut self) -> Result<(), RuntimeError>

pub fn exceed_end_of_head(&self) -> bool

pub fn skip_token_and_colon_and_exceed_end_of_head( &mut self, token: &str, ) -> Result<(), RuntimeError>

pub fn token_at_index(&self, index: usize) -> Result<&str, RuntimeError>

pub fn current_token_empty_if_exceed_end_of_head(&self) -> &str

pub fn current_token_is_equal_to(&self, token: &str) -> bool

pub fn token_at_end_of_head(&self) -> &str

pub fn token_at_add_index(&self, index: usize) -> &str

impl TokenBlock

pub fn new( tokens: Vec<String>, body: Vec<TokenBlock>, line_file: LineFile, ) -> TokenBlock

Trait Implementations

impl Clone for TokenBlock

fn clone(&self) -> TokenBlock

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for TokenBlock

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for TokenBlock

fn eq(&self, other: &TokenBlock) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
