Struct rune::TokenStream

pub struct TokenStream { /* fields omitted */ }

A token stream.

Implementations

impl TokenStream

pub fn new() -> Self

Construct an empty token stream for testing.

pub fn from_to_tokens<T>(tokens: T) -> Self where
    T: ToTokens, 

Construct a token stream from tokens.

Panics

This will panic if called outside of a macro context.

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

Push the current token to the stream.

pub fn extend<I>(&mut self, tokens: I) where
    I: IntoIterator,
    Token: From<I::Item>, 

Extend the token stream with another iterator.

pub fn kinds(&self) -> Kinds<'_>

Return something that once formatted will produce a stream of kinds.

Trait Implementations

impl Clone for TokenStream

fn clone(&self) -> TokenStream

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TokenStream

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

Formats the value using the given formatter.

impl Default for TokenStream

fn default() -> TokenStream

Returns the “default value” for a type.

impl Eq for TokenStream

impl From<Vec<Token, Global>> for TokenStream

fn from(stream: Vec<Token>) -> Self
