TokenSlice

Struct TokenSlice 

Source
pub struct TokenSlice { /* private fields */ }
Expand description

トークン列からトークンを供給する実装

マクロ本体などの既存トークン列をパースする際に使用

Implementations§

Source§

impl TokenSlice

Source

pub fn new( tokens: Vec<Token>, interner: StringInterner, files: FileRegistry, ) -> Self

新しい TokenSlice を作成

§Arguments
  • tokens - パースするトークン列
  • interner - 文字列インターナー(既存のものをクローン)
  • files - ファイルレジストリ(既存のものをクローン)
Source

pub fn position(&self) -> usize

現在位置を取得

Source

pub fn remaining(&self) -> usize

残りトークン数を取得
