Struct moparse::TokenCollection

pub struct TokenCollection { /* private fields */ }

Represents collection of Modelica tokens generated by the lexer.

This object is used in the parsing process. Afterward it should be used together with the list of syntax events to produce parse trees or ASTs.

Implementations

impl TokenCollection

pub fn new() -> Self

Return a new empty token collection. Should be called by the lexer.

pub fn len(&self) -> usize

Return number of all lexical elements in the collection.

This function doesn’t discriminate between semantically meaningful tokens, comments and lexical errors.

pub fn is_empty(&self) -> bool

pub fn token_count(&self) -> usize

Return number of semantically meaningful tokens, ie. not comments and not errors.

pub fn comment_count(&self) -> usize

Return number of comments.

pub fn error_count(&self) -> usize

Return number of lexical errors.

pub fn get_item(&self, i: usize) -> Option<&Token>

Return i-th item (token, comment or error). Return None if there is no such item.

pub fn get_token(&self, i: usize) -> Option<&Token>

Return i-th token. Return None if there is no such token.

pub fn get_comment(&self, i: usize) -> Option<&Token>

Return i-th comment. Return None if there is no such comment.

pub fn get_error(&self, i: usize) -> Option<&Token>

Return i-th error. Return None if there is no such error.

Trait Implementations

impl Default for TokenCollection

fn default() -> Self

Returns the “default value” for a type.
