Struct TokenStream

pub struct TokenStream { /* private fields */ }

A token stream.

Implementations

impl TokenStream

pub fn new() -> Self

Construct an empty token stream for testing.

pub fn push(&mut self, token: Token) -> Result<()>

Push the current token to the stream.

pub fn extend<I>(&mut self, tokens: I) -> Result<()>

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 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 From<Vec<Token>> for TokenStream

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

Converts to this type from the input type.

impl<'a> IntoIterator for &'a TokenStream

type Item = &'a Token

The type of the elements being iterated over.

type IntoIter = Iter<'a, Token>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl IntoIterator for TokenStream

type Item = Token

The type of the elements being iterated over.

type IntoIter = IntoIter<Token>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl OptionSpanned for TokenStream

fn option_span(&self) -> Option<Span>

Get the optional span of the type.

impl Parse for TokenStream

fn parse(p: &mut Parser<'_>) -> Result<Self>

Parse the current item from the parser.

impl PartialEq<TokenStream> for Vec<Token>

fn eq(&self, other: &TokenStream) -> 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.

impl PartialEq<Vec<Token>> for TokenStream

fn eq(&self, other: &Vec<Token>) -> 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.

impl PartialEq for TokenStream

fn eq(&self, other: &TokenStream) -> 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.

impl ToTokens for TokenStream

fn to_tokens( &self, context: &mut MacroContext<'_, '_, '_>, stream: &mut TokenStream, ) -> Result<()>

Turn the current item into tokens.

impl TryClone for TokenStream

fn try_clone(&self) -> Result<Self>

Try to clone the current value, raising an allocation error if it’s unsuccessful.

fn try_clone_from(&mut self, source: &Self) -> Result<(), Error>

Performs copy-assignment from source.
